Did she give you a due date? And you being 11 weeks would make your conception date around the 28th of July so I'd say current bf
You do know, I assume, that the doctor's count of "weeks pregnant" does not begin when you conceived, but two weeks earlier, on your [assumed] first day of your last period? The doctor does not think you were pregnant on day 1 of bleeding, but they begin the count on that day since bleeding is an obvious signal where ovulation is not obvious. The doc is telling you that you conceived at the end of June.
She said the estimated due date is April 18,2016
The first day of my last period was in July on like the 13th so does that mean that I still conceived at the end of June?
Sorry, typo, meant the end of July, not June. Like everyone is saying all the calculations come out as being around July 28.
