So confused, please help.

My husband had the snip 11 years ago after 3 children together. All samples since showed zero sperm. We split up as of September 2011 and I had a one night fling with someone else the last week of October 2011. I am currently 28 weeks pregnant, I have had two scans confirming all is ok. The reason for the confusion is, going by scan and lmp (the last i can recall) the scan means I conceived end of July/first week or so of August 2011 with my husband but he doesn't produce sperm any more. The only other sexual contact I had was the guy at the end of October, but if this were his baby then I would be more like 15/16 weeks along. That's a massive difference. Can the doctors scans be that wrong?? Please someone offer some advice, I feel on the verge of a breakdown with no one to talk to and am desperate to try and get back with my husband.

I will also add that the one night fling did use a condom.

Is your current due date around Apr. 7?  

By my calculations,  you conceived around July 12.  (remember,  when the medical community says you are 28 weeks pregnant,  you conceived 26 weeks ago.  They begin calculating the gestation from the first day of your last period.  So your last period was around July 1,  they believe.)

I'm curious about why you didn't realize you were pregnant before you had sex with the October guy.  At that time,  you would have been about 12 weeks pregnant - nearing the end of your first trimester - through with all the nausea,  sore boobs,  and starting to show.  Since you've had three children already,  it's a surprise you didn't recognize you were that far along,  if you were.

When did you first have a positive pregnancy test,  and scan?

Hi,thanks for your comment, my last period that I remember was middle of July, and my due date is beginning of May. I had been putting the lack of periods and all other symptoms down to the stress of husband and I splitting up, i also lost loads of weight, and when he left I was heartbroken so wasn't really thinking straight at all (hence the one night stand) I found out when I was about 16 weeks and first scan at 18 weeks. In hindsight, yes I had symptoms but as hubbie had had a vasectomy it didn't really cross my mind.

You're right - I counted wrong.  I get around May 5 when counting again.

I think it's almost certainly your husband's baby - but you'll probably want to do a DNA test when the baby comes.

The funny thing is, had my husband not had a vas, I wouldn't even be questioning these dates at all, there are so many weeks in between when I am being told I concieved to when I had the one night stand, not just the odd one or two weeks but several. I thank you for taking the time and reading and replying to my question, so much appreciated :)
