Can my girlfriend be pregnant and when should she start her period?

I don't think the NHS will report anything unless they have concerns. I also don't think you would be sent to prison just for the under-age sex. I think the 'worst' that would happen would be having to sign the sex offenders register.
If she is pregnant, the option of abortion might arise, but I would strongly advise against that. Apart from the health risks, there are psychological effects, and many who have terminated bitterly regret doing do. The best and most mature option would be for you both to accept your responsibilities and go through with the pregnancy. The options are then to keep the baby or offer it up for adoption. I would suggest that you get married and give the baby a secure environment in which to grow up. You didn't say where you live (where?), but there are support agencies about, and it sounds as if your girlfriend would have support from her family. I would suggest contacting 'Care for the Family' and get advice and support from them.
What is important is to review how this all came about (you didn't answer all my earlier questions!) to ensure you don't make the same mistake again. How is your girlfriend coping with all this?
I hope this helps

Hello Shepherd,

Just a quick question. I got the date of her late period wrong. She usually comes on on the 17th of each month and she has a 4 day period therefore she'll normally 'bleed out' on the 20th, but in January as I said she was late. I said that she 'bled out' on the 30th, but she actually CAME ON on the 30th Jan but she can't remember the date that she 'bled out'. She said it was either the 1st or 2nd Feb, she's not entirely sure.

Just wondering with us having unprotected sex on the 9th Feb, would she have been fertile and what are the odds of her being pregnant?

Thanks,
Smithy.

If she started her period 30th Jan, and has a 30/31-day cycle, then the chances are that 9th Feb was just outside her fertile time, so the chances of ensuing pregnancy are low.
However, if she has a shorter period (she ovulated a day or so earlier), it could have been a fertile day.

So what would her ovulation date be for the 9th Feb to be just outside her fertile time? I have no idea when she should come on her period, because she normally comes on the 17th of each month, so wouldn't that be a 28 day cycle?

In order "for the 9th Feb to be just outside her fertile time", she would probably have needed to have ovulated on 7th or 15th Feb. Those dates would point to a period starting 21st Feb (tomorrow) or 1st Mar.

"she normally comes on the 17th of each month, so wouldn't that be a 28 day cycle?" No, because the only month to have only 28 days is February. From 17th Dec to 17th Jan is 31 days; so is Jan-Feb, Mar-Apr, May-Jun, Jul-Aug, Aug-Sep, and Oct-Nov. But 17th Apr to 17th May is 30 days; so is June-Jul, Sep-Oct, and Nov-Dec. So if "she normally comes on the 17th of each month", she must have a 30/31-day cycle.

Oh right I understand. So because she has a 30/31 day cycle then do you think that there will be little chance of her being pregnant? Based on the dates and all the information I have given you

Not really. Because her last period started on 27th Jan her next period would be expected 27th Feb. That would presume ovulation on 13th Feb, so 9th Feb would be a fertile time. But her last period was delayed (indicating a delayed ovulation) so it is possible this month's ovulation was delayed also. If it were delayed by 2 days or more, then 9th Feb would not be a fertile day. However I don't feel the chances are very high.

No not the 27th, her period in January STARTED on the 30th. So her expected period would be around 1st or 2nd March? Does this mean that because she started on the 30th then the 9th wasn't a fertile time?

Sorry about the wrong date! Your assumption is right. In fact I answered that previously when I said:

"If she started her period 30th Jan, and has a 30/31-day cycle, then the chances are that 9th Feb was just outside her fertile time, so the chances of ensuing pregnancy are low.

However, if she has a shorter period (she ovulated a day or so earlier), it could have been a fertile day."

In fact, with a 31-day period, her period would be expected to start 2nd Mar and 9th Feb would not likely be a fertile day.

Sorry for the late reply, I actually replied to your last message twice, but the internet on my phone is being ridiculous.

Oh yes of course you did answer my question! I'm sorry about that.

I've just got three more questions for you if that's okay?

1) Just wondering, because she has always had a 30/31 day cycle, will she more than likely still have one this month? Also does this mean that she should expect to 'come on' her period on the 1st or 2nd March?

2) I know I've asked you this a few times, but I'd just like a straight up answer if that's okay. After everything I've told you, that she normally has a 30/31 day cycle and that we had intercourse on the 9th Feb. Do you think that she is pregnant? I'm just stressing myself out a LOT. I know it's my own fault because I didn't do the right thing and wear protection, but I just need a little reassurance please.

3) How many days before she 'comes on' her period should she start to experience stomach pains?

1. It is difficult to say, because I don't know what cause the 10-day delay last month. But, all things being equal, I think it is probable she will still have a 30/31 day cycle and so come on her period 1st or 2nd Mar.
2. I do not think she is pregnant from all you have told me.
3. The stomach pains should start about the same time before her period as usual.

Sorry again for the late reply, I've been awful busy the past day or two.

1) The delay last month was probably due to stress, that is what we think and that is what the doctor thinks. Does that mean that her period will still be on the 1st or 2nd Mar. or does it change things?
2) Oh good! Just a random question, do you think that if I did ejaculate inside her, what would the odds of her being pregnant be then? Because it wasn't on her fertile day.
3) Oh right, thank you.

1. If it was stress, then just as stress may have affected her previous period, so stress might affect this period.
2. The definition of a fertile day is one where sperm introduced into the vagina has the potential to fertilise an egg. The estimation of which are fertile days is taken from medical research. Sperm is reckoned to be potent for 5-6 days. It is possible that some might survive longer. Some think that 7 days is the limit. Released eggs are reckoned to be viable for about a day; some say up to 24 hours. The additional problem is knowing exactly when ovulation has occurred to estimate the fertile days. That being so, there must be a greater chance of one sperm out of millions in an ejaculation reaching and fertilising an egg than one sperm out of maybe several hundred in pre-ejaculatory fluid. Also, an ejaculation is likely to deposit sperm nearer the cervix than pre-ejaculatory fluid oozing out. That also depends on depth of penetration. You must realise that anytime you have sex there is a risk of an ensuing pregnancy because the reproductive system does not always conform to pattern.

1) But without stress should her period 'start' on the 1st or 2nd?

2) Oh right, I understand. If she was pregnant, would she be showing symptoms of pregnancy just yet or would they start later?

I don't think she is pregnant at all, I just want her period to start so that I can stop worrying.

1) The indications are that it is likely to start at the beginning of March.
2) If she were pregnant, there is the possibility she might have symptoms, but not everyone has them, and often when they do, not this early.

*As it is over a fortnight since 9th Feb, a pregnancy test should be quite accurate now, which you could consider as you are worrying.
