What should I do??

So I've been dating my boyfriend for 2 years and some change now. He wants a child badly and every time we have sex nothing ever works.

I tried pearls and I went to the doctor she said I had a BV,But I feel like something more than that may be wrong but I'm not sure I really hope not.

We kept trying and he would get Mad and say if I can't have children for him he will find someone else. When I hear these words I get worried and reallllly stressed out. I would cry most of the time he said that or I would stay up half the night to ball my eyes out. In all this I'm still really stressed out because I want us to last because I love him. What should I do???

But I'm still looking forward to having a baby I'm still trying and I'm trying to be positive about the whole thing but it's hard.

I'm currently TTC if any one have advice for me please let me know I need the help
