The first day of my lmp was on 4th April,I had sex with my ex boyfriend
on 10/11/12/15/16/17 April but regretfully had sex with someone else on 19th April.Did a hpt on 7th May & was positive.Went for u/s on 14th May & was advised I am 5-6 weeks pregnant but have to go back on 21st as they need a definite gestation period.I am in such a quandary as if I could be certain is my ex boyfriends maybe we could make a go of it.When I went for u/s couldnt remember date of lmp & gave an approximate of six weeks ago. The sonographer advised me that if I any less than 5/6 weeks then wouldnt have shown up on u/s but does she mean 5/6 weeks from my lmp or the size of the foetus is 5/6 weeks from date of conception?
Any advice would be most helpful!
