Which day should I go by? Dated 8 weeks during early ultrasound but according to LMP it should be 8weeks 3 days.Sonographer took several measurements and they all measure 8 weeks.

3 days doesn't make a difference. Dating whether it be by LMP or ultrasound can actually be 2 weeks earlier or two weeks later.

Thank you for your reply :).

Yes, I am overly surprised that they were that close, There is no exact date. The date, either of them could be give or take 2 weeks

I agree. Could it be that I ovulated later than usual?

I don't see how ovulation matters at this point. Your dates are only 3 days off. That's about as accurate as you are going to get.

I was just curious.

Actually 3 days is the most accurate I have ever seen!

Apparently, the sonographer went on to tell me that she took repeated image shots of the fetal measurements which returned the same 8 week O day measurement. Anyhow I was mostly curious because I was on birth control before I got my last period so I had somewhat of an idea of when my,lmp was either 14 or 15 of June but wasn't sure.

Oh, girl! Prior to me becoming a nurse I was on birth control. Used it perfectly along with a condom. Got pregnant not once, but twice.

At a later age I was told that I was going through an early menopause, my daughter is now 19.

Even later I went through cancer and chemotherapy. The chemo I had to take makes a woman sterile. That was 15 years ago and my youngest son is now 10. I then became a RN specializing in women's heath.

As you can see, there is no form of birth control aside from a total hysterectomy or complete abstinence.

Indeed. Maybe I pick your brain since you have the medical background? Could I have ovulated being that I was on birth control?

While it's not common, it is possible. Did you take it at the same time every day? How long were you on it, i.e. how many years/months?

Was only on it for one cycle. Actually started period a day before my last pill.

Last pill being an active pill.

Oh, well then yes, of course! For the pill to be active at the most peak levels, you need to be on it for at least one month, preferably two before having sex without other forms of contraceptive. Basically you weren't on the pill long enough for it to be effective.

I wasn't. Neve started a new pack because of insurance reasons. Did use condoms but they too aren't foolproof.

You were basically not on any birth control, the pills while having some effect were not fully active. Condoms have a 3 to 10 percent failure rate as normally used.
