I'm pregnant! Who's most likely to be the father?

The guy who cummed inside you is most likely the guy who's the father.

Dear eln

A week after any of your fertile days is not likely to be a fertile day. As pre-cum can contain sperm, it is possible that the first guy is the father - whenever you have sex there is the risk of pregnancy. But you may have mis-assessed your fertile days. But you don't give any dates to make an informed judgement.

1. When did your last period start?
2. What is your cycle length? Is it regular?
3. When was your next period expected to start?
4. What was the date you had sex with guy1?
5. What was the date you had sex with guy2?
6. What is your due date for the birth?

Dear eln

With a 26-day cycle you are likely to have ovulated on 1st Dec. On that basis Guy 1 would be the likely father as he was the only one you had sex with by then.

However your November period was 4 days late, so your December period might have been geared up for being late also.

If it were geared up to be 4 days late again, then that would have been because you ovulated 4 days later (i.e. 5th Dec). On that basis Guy 1 would still be the likely father.

If it were geared up to be 5 days late again, then that would have been because you ovulated 5 days later (i.e. 6th Dec). On that basis Guy 1 would again be the likely father. If you ovulated any time between 1st and 6th Dec, Guy 1 would be the likely father. Sperm are likely to live for 5-6 days in your body.

But, if your period were geared up to be 6 days late, then that would have been because you ovulated 6 days later (i.e. 7th Dec). On that basis Guy 2 would be the father.

The only other consideration is whether you had any other sexual activity whereby sperm might have been transferred to your vagina without sexual intercourse.

The due date for the baby is calculated 40 weeks from the start of your Last Menstrual Period (19th Nov), as that is the only certain date.
