What do I do😞

I just found out I am 5 weeks pregnant. Only two months ago I had a miscarriage. My boyfriend and I agreed I would go on birth control until we were really ready again. My cycles the last two months weren’t normal so I was going to start my BC this month. He doesn’t seem happy because we discussed waiting.... it’s a shock to both of us. I really want to be happy, but it’s hard. He says the only reason he isn’t all happy like that is because he is scared it will happen again. But I feel so uneasy. I’m obviously sensitive and emotional right now so the fact that he is blah about everything is giving me extreme anxiety and making me panic more.... Idk what to do my head is all over the place. Wish I could find some peace somehow😥
