Pregnant. The man doesn't believe it's his because we've been in a bad relationship and had sex once in the last month. So he doesn't believe it's his.

I haven't been with anyone, I haven't cheated. But it's not nice and I don't know what to do.

Instead of joy about the event just some suspicions, groundless accusations, doubts. How can I convince him that the baby is his? Why is he so distrustful? This makes me feel very hurt.
