I had sex with GUY A a day or two before my period which came Sept 23.
My period was regular, normal flow and lenght.
Then after my period I had sex with GUY B and only GUY B up until I found out I was pregnant around Nov.
I had a couple of dating scans one at 6 weeks and other at 9 weeks. Both were on schedule for me to have a due date of June 30th until I got around 20 weeks when they changed my due date to June 21st based upon a ultrasound.
I just need some ressurance that guy b is the father.
oh and my period before my Sept 23rd one was Aug 26th.
