I am pregnant but I am not quite sure who the father is of my unborn child.

Based on one of the apps it says my fertil window was may 20-25

Your cycles are quite irregular.

• 21 Jan 2017 to 26 Feb 2017 = 36 days
• 26 Feb 2017 to 18 Mar 2017 = 20 days
• 18 Mar 2017 to 17 Apr 2017 = 30 days
• 17 Apr 2017 to 13 May 2017 = 26 days

These range from 20 to 36 days, so are you sure Feb period started 26th and not (say) 20th?

However, the average is 28 days. That would project to a June period being perhaps due on 10th. That would be consistent with your test results.

If the due date is an accurate assessment from the scan (rather than a projection from your LMP), then conception on 27 May (Ovulation Day) would seem likely, and 22-27 May would then be likely fertile days.

The app would probably be taking the average of the last 3 cycles. It would alter your due date by -2 days and would then put 20 May encounter as a possible cause. However, that would mean a paternity test would be needed. But the apps are only a guide based on recent period history, and your cycles are irregular.

Was your scan abdominal or vaginal?

If you are due for another scan soon, ask about the due date from that new scan, and discuss the conception possibilities with the medical practitioner.

It was a app I been using since I got off nexplanon last year in July tracking my periods. They are irregular. The app says it was a average of 27 day cycle and I was fertile the 20-25 of may. It was a pregnancy clinic not a obgyn that did the transvaginal ultrasound. I used a app and put in my last period which was may 13 and it brought the due date and conception date that was given there and also brought the fertile days as the other app. I go July 18 and read the ultrasounds are accurate between 8 and 18 weeks and read sperm can live up to 7 days? I am getting the DNA.

Transvaginal scans are the more accurate. But the DNA should be 'conclusive'.

So reading everyone's comments made me more somewhat comfortable about talking about it because looks like we were all in the same boat in our life. So I am currently pregnant and I don't know the exact date when i conceived. I had a one night stand on Dec. 18 and I had gotten back with my ex on the 21st of Dec. My ex and I had sex multiples times up until the 29th of Dec. My last period was on Nov. 25-30th. The doctors said I was 6 weeks when I went in on Jan. 14th.. I am freaking out because I still don't know who the father may be. To me, it would make sense if it were my ex, but can I please get anyone else's opinion ?

You need to give some more information as period LMP date is not enough.

1. What is the length of your cycle usually?
2. What are the dates your previous 5 periods started (or as many as you know)?
3. What date did you expect your Dec period to start?
4. What other dates did you have sex in 2016 after Nov 25?
5. How was your "6 weeks" determined when you 'went in on Jan. 14th"?
6. Have you had a scan? If so, when, and was it abdominal or transvaginal?
7. Have you been given a due date?

 

Hello i have questions about my pregnancy as well i normally come on my cyle around the 13th or like the 15th & it last a good 4 or 5 days well im 28w1d lmp was 1/13/2017 but it lasted like two days , went to the doc kinda late my first ultrasound was at a pregnancy hotline they went by my LMP well my 1st OBGYN appt i found out by the abdominal ultrasound i was two weeks off my due date went frm 10-20 to 10-07 i went with the 10-07 simply because the baby measurements and size was right on point but my new due date but that would put my lmp @ dec 31 & conception around jan 14 wen i was supposed been bleeding this is my 2nd child my daughter is 3.5 with her i had one last period while i was pregnant so im thinkin the 10-07 is right but den again it just dont add up to me. My ex i was with for a 1 year we broke up around jan 14 got bck together jan 23 had sex he came in me i thought i peed it out we always used the pull out method the whole year we was together . well while my ex and i were broke up me acting outta lust i had unprotected sex with another guy the night before me and my ex got bck together well basically the same day it was like 1/23 @ 2am or some he also nutted n me im so confused according to my 10-07 my ex would most def be the father he is the only man beside the one night stand i been with but witb the 10-20 date the father could b either one and my ex is the supportive one and its crazy cause even in my bbys ultrasound pictures my bby had my ex features but it could also be the one night stand guy bby to ? Confused ??? But not ashamed my ex and the one night stand guy both kno the situation my ex claims the bby and the one night stand guy is MIA but he never denied the bby either :( dont have long to actually see and find out i jus dnt wanna hurt my ex hes claiming the bby

I have a good feeling about it being my ex but it just cause i had a one night stand it still crosses my mind just a mistake i learned frm thank god i was clear and std free i learned frm that ill never make choices like this outta lust and hurt anymore !

What was the out come

1. Length of cycle is usually 5-6 days. & 33 days apart. 2. October 23rd, 2016.
3. My expected cycle date was December 27th. 4. I had sex on December 18th, 21st, 23rd, 24th, 26th & 29th. 5. It was determined through transvaginal but I found it odd because it would have meant I most likely conceived on December 9th, which I was far from having any sexual intercourse. My due date is "September 9th."

& I also had not gotten my period through June 2016-September 2016. So October was my first sine May 2016. Thats why I don't have many periods to say before this pregnancy.

The dates are rather confusing.

If your LMP were 13 Jan (presumably when expected), then with a 28-day cycle your due date would be projected to 20 Oct. That would assume conception (ovulation) 27 Jan (fertile 22-27 Jan). However, with periods usually starting on 13th-15th, it would suggest cycles more like 30 days long.

A due date 7 Oct would suggest conception (ovulation) 14 Jan, but that would mean that your Dec/Jan cycle was going to be 6 weeks rather than 4, assuming Dec period started around mid-Dec.

Today being 17 Jul would make 197 days (28w1d) ago = 1 Jan. So, depending on the method of reckoning, it could indicate a due date of 8 Oct.

1. What were the start dates of your last 6 periods (or as many as you know)?
2. What is the latest due date, and how was that calculated?

The due date of 9 Sept suggests conception (ovulation) on about 17 Dec, so sex on 18th Dec is a possibility.
LMP 25 Nov with a cycle of 33 days gives expected ovulation date of 14 Dec, but it could have been delayed by 4 days - you have been irregular!

Period always come around the 12th -15th of each month and my latest due date is oct 7 thats what im goin by but that would put my lmp dec 31 thats where i got confused at
