Pregnancy and Conception Date

[krushing]

Ok, I may sound stupid, but I don't know any better.  I found out I was pregnant in March of this year, which ended in a miscarriage.  But that is not the point.  How do you know when you conceived.  I had not had a period since Janaury because I took strong antibiotics twice at the end of January and in February.  So, I did not have AF in February or March.  I thought it was from the antibiotics, but just for curiousity, I took a hpt in March and it was positive.  The doctor said the sac measured 4 weeks.  But in situations like that, when do you know.  How do you keep up with that?

I have never heard that antibiotics can affect your period, (except to make it a little less bacterial if it were LOL).  So you may need to count from before the antibiotics.  But I'd take the doctor's estimate as pretty good, maybe off by a week.  As the scans and so forth go on, they will be able to try to narrow it down a bit, based on standard size of the baby at those points. That's about all you can do to get a date, if you genuinely have no idea and a wide time range when it could have happened.

Sorry, I wrote that as if you were talking about a current pregnancy, and now I see you were analyzing the one that went by.  The main hint to take now is to use a way to measure your ovulation, if you are presently trying to conceive.  Either temping or the ovulation test kits that are available will give you a pretty good idea, and it's good info to have.  -- A.
