The sonar measured the baby and currently 9weeks and 4days. Thing is I would like to know when i conceived. I had sex on the 26, 27, and 29 of february but I also had sex on the 19th and the 21st of February. I took a pregnancy test on the 09 March and it was negative took one on the 22nd March it was positive. I started getting signs the week 15th March. Does Measuring the baby give the exact day of conception if one counts back? I have a very irregular period which is about 39 days, have missed a month once. I last had my period on the 23rd of Jan. I need to know if conception happened by the 19th or by the 26th? Thanks
But I tested on the 09th and it was negative. The test should have shown positive if it was the 19th intercourse. Also why i say this is that the sonar shows 9weeks and 4days and due date being 26 Nov. If I was missing the month of february that would mean that I was most fertile first week of March. Is it not. There were also no signs or anything till the week of the 15th. Dont now but something tells me it is the first week of march. I could be wrong thou.
There is absolutely no way to tell which date (or group of dates, in this case) caused you to get pregnant because your cycle is so irregular. Ultrasound measurements are different than how far along you are based on your LMP. When I was pregnant my ultrasound measured me two weeks behind my actual pregnancy. I'm sorry, but you'll have to get a DNA test to know for sure.
