If your last period was normal, most likely you got pregnant in the first or second week of April. If it was an unusual period or your cycles are super irregular, you might have gotten pregnant at a different time. Did you have an ultrasound early in pregnancy? If so, did they tell you how many weeks they thought you were from the first day of your last period? And did they give you an estimated due date?
Most likely April but you never know.
My due date is December 31st
April ... When I went to the clinic my due date was Dec. 25 and I conceived in April
My lmp was 22 March, edd 26 Dec, conceived 4 April.
So it was definitely the sex in april?
Honey, how did you get your due date, was it from an ultrasound? If it was just from looking at the calendar and counting from your last period, that is not the kind of method that allows someone to say "definitely."
If your due date was from an ultrasound measurement of the baby, the other question is, how early in the pregnancy was the ultrasound? They are more accurate for dating the pregnancy in the first trimester than they are later.
Long story short I didn't know I was pregnant until July 3rd. I went and got my 1st sonogram July 15th and they told me I was 16 weeks
By the ultrasound, you would have conceived within a week either direction from April 8 or 9, meaning from the 1st through the 15th. Don't worry that you conceived in March before your last period. Are you worried about sex in March after your period?
My lmp was also march 26 and I conceived april 9. I only know this because we tried to get pregnant, and that was the only date we had sex where he did not pull out.
