i had 3 early ultrasounds that dated me within each other

15th sept - crl 12.5 mm 7 and half weeks
27th sept -crl 30.7 mm 9. 5 days (due date 27th april)
18th oct-crl 65mm 12 (due date 26th april)

bearing in mind with the 27th ultrasound i did not give the lmp only with the 18th oct dating scan


is there a chance that i fell pregnant from intercourse on the 3rd July??

i am fairly certain my lmp 18th july i had intercourse on the 24th july and august the 7th

which of these events do you think caused he pregnancy

August 7th would be the closest guess being Your ovulation days would be July 27-august 8th

How long are your cycles usually? I'd guess at August 7th, if you had a period 18th July after you had intercourse on the 3rd then you could not have gotten pregnant from intercourse then as you wouldn't have had a period if you were pregnant. So it would be either 24th or 7th but I would guess at 7th unless you have a short cycle?

EDIT: In that case I would definitely say 7th August. Congratulations :)
