Working out conception date dating scan average age of people on dating sites
also feeling alot of twinges and pulling sensations which i don't remember first time around is this normal? x Well they always calculate due date based on your period. If you know your exact date of conception you either add 2 weeks to that date or just count 38 weeks from that date. So technically speaking a women is never actually pregnant for her first 2 weeks. Remember: even if you could narrow conception down to the hour (which is impossible because you could've ovulated a day later, and sperm can live for up to 72 hours, viably, inside of you) it's still an EDD (estimated due date). They won't wait for a certain date so it really doesn't matter if you count 38 weeks from conception, or 40 weeks from LMP. .i know that can happen but i have 28day cycles..my scan put me back 2 weeks.So according to my dates im nearly 2 weeks over haha..have to go with the fact that i really was going to have a 40day cycle! Im assuming this baby will come when she wants.unlike you im the other way..chance of her coming earlier whereas you might not be as pregnant as they think.slept together, I wrote it down and it was the week of valentines- 9th feb....now im thinking I might actually still be preg until mid Nov with MW's stressing about me being overdue and not letting me have my homebirth....was 15th january, only dtd on the 1st of febuary and the 14th of febuary...should have been due on the 15th of febuary..it would seem i concieved 14th!we're certain that this isn't possible but as its our first baby we wondered if anything similar had happened to anyone else, or if this is quite common.they've booked us in for another scan in 3 weeks but im convinced they're wrong, is it possible to just have a small baby??katy I went into my dating scan thinking I was 12 weeks and 3 days but I was only 11 weeks and 3 days.
Scans are more accurate than using the LMP and, if the scan date differs from your period dates, the scan date will be used.
so it would appear i ovulated the day my period was due so my cycles were obviously a bit mixed up.
