Makes so much more sense! thank you so so much and now I feel so happy to know that my current boyfriend is defiantly the father now (: good deal. Thanks so much!
That's correct, odd as it may seem. The two weeks computed between the conception date and the assumed first day of the last period, are a standard allowance they give to everyone whether the woman's cycle is long, short or irregular. What they are saying is, we see this baby, and its milestones and size are consistent with the size of an embryo that is 7 weeks 1 day which includes 14 days allowance at the front end. (This means that if you're told you're 7 weeks 1 day "along," you are 5 weeks 1 day from conception.)
Regarding whether they give you a different due date later in your pregnancy , don't worry. Only early ultrasounds are very accurate for dating, because babies grow at (or can grow at) different rates. Everyone starts out as one cell and divides to two and then to four, at a known rate. But after a while, one baby might grow a little faster and another might grow a little slower than average. Go with your 7th week ultrasound, it is the most reliable for dating the pregnancy.
Thank you so much im so relieved too hear that it's my boyfriend! <3 but I had another question, they said my first ultrasound at the 7 week and 1 day they said my due date would be march 15 which matches my period but now my due date is march 30th 2014. Is he still the father no matter what due date they go by? cuz if you go by my period it says I was ovulating differently or something.. Or does it not matter because the 7 week and 1 day thing told them i conceived around the 6th of july? and does it matter that they just "guessed" i had a period on june 22 even though i didnt have a period that day my last period was june 8th.
Your story all adds up to your current boyfriend. It would be pretty hard to get pregnant from fingering if the guy only had pre-ejaculatory fluid on his fingers, and besides, that fingering was too early (based on the size of your embryo at 7 weeks 1 day), and you did have lots of unprotected sex in the right time range with the boyfriend. If it's going to worry you, you could get a DNA test when the baby comes, but unless you need one for the courts (for child support) you could just do it with an over-the-counter test.
