I probally dont have any business talking about it but I do have a slightly revelant statement.
My mom acted like this when she got pregnant with her new husband.
It was a still born but anyways my mom acted the same with my her husband I think its the timing and whats all going on.
Just stick around and hang it out maybe some counseling would do some good anything positive is a good thing.

I bet that baby is going to be beautiful and when it does come you can be proud of yourself as a person and a mom.
