Long post but need advice and to vent.

So about 8 months ago me and my high school sweetheart got back together. 6 months ago I moved 2 hours away from my hometown to move in with him. Before my move I mentioned how I needed to get back on birth control ( I wasn't sexually active before him for over a year) and he said no. He said he wants to have a baby and if it happens it's meant to be. So within 2 weeks I'm pregnant. We are both excited and freaked out. We took 5 tests all positive went to the doctors had blood work done and everything came out positive and good. Told both our families. His was supportive and mine was not. His family said we should move in with them (dad, stepmom and stepbrother) so we can save and buy a place not rent and they could help out with the baby. So we move again. Mind you I have only met his family a few times so it was uncomfortable but they were sweet and welcoming. At 10 weeks I go to my first ultrasound and the doctors sees nothing. No sac no baby no one ever explained to me what happened. I was devasted. We told his family and both decided it's probably for the best since we weren't as finically ready as we wanted to be. I got on birth control right away. But I told my boyfriend I should get the shot or IUD because I always forget to take the pills he said no. We start having sex again almost immediately and I skipped a couple days and then misplaced the pills and stopped taking them all together. He knew and was still haven't unprotected sex with me and came inside me. I kept saying I thought I was pregnant and he doubted it. One day while he was at work I took 4 pregnancy tests. They all came out very dark and positive. I told him and his response was just "ok". He didn't seem excited or anything literally zero emotion. I made an appointment for my first ultrasound it's in less than two weeks I will be 10 weeks by then. And he keeps making comments like I don't want to have a baby under my parents roof. I'm not ready. He's basically implying I trapped him yet he knew I wasn't taking the pills and still had sex with me. I'm excited but it's hard to be happy when he's so negative. Before he wanted a kid and a family so bad but after my last pregnancy everything changed. Now I feel like I'm forcing him to be a father when he's not ready. He knows I won't get an abortion so it's like well I'm pregnant so saying you don't wanna be a dad isn't gunna help now. What do I do?
