sticky situation

So, me and my husband are now speperated and it's been a hell of a show cause we have an almost 2 year old together. And we can't just get along it's always drama! Sometimes about one being with another person and sleeping over or  the other not spending time with the baby. Well before we split we were trying to conceive, and then we split up and a week later we had sex one day unprotected and came inside... I haven't had my period in like 3 months....
