I had sex on the 29th of September with guy A
I'm unsure if it were inplantation bleeding or a period which was on the 7th of Oct
After my period or inplantation I had sex with guy B multiple time
My due date is July 15.
Have they given me this due date because I told them my period was on the 7th so they go by that?
Or does the sonogropher simply go by the measurements of the baby?
At my earliest scan I was 9w 5d
