I have a boyfriend and me and him have been trying to conceive for a few months. In February we separated for about a week and I had sex with an old friend and I took a home pregnancy test and my period came about a week later. Since then I've had 2 periods and Now I'm pregnant , I only missed one period which was last month, I'm not sure how far along I am right now but I'm a little scared at the moment because my old friend asked what if it's his . What should do ?
