Struggling

I’m struggling so much right now with my emotions and hormones during the first trimester of pregnancy. This is my first baby and I feel like it’s taking such a huge toll on my marriage. I have an almost 4 year old Step daughter but this is my first pregnancy. I feel like I can’t have a serious conversation with my husband without it turning into a fight. I feel like he’s the least emotionally supportive he’s ever been. I don’t know if my being pregnant is like stressing him out a lot or something. We planned this baby and we had been actively trying. But he’s been so weird the last few weeks. I try super hard to voice my opinions or concerns in the best way possible and I literally start every conversation by saying “bare with me I’m trying to explain myself as best as I can” or if I can tell I’m really emotional or struggling I let him know beforehand. I feel like a total psycho most of the time though like I can’t explain myself without coming off as a total bitch. And I keep trying to explain that I’m trying and that I’m not aiming to be totally crazy, but he gets super mad or shuts down every time. Like I can’t talk about anything without feeling like he’s telling me I’m ridiculous or over reacting or causing drama or making things worse. But he gets even more upset when I don’t talk. Like he’s constantly prying and bugging me about why I won’t talk or what he’s done wrong or whatever. And then I just get mad or start crying or both because I feel like any time I try and talk we argue. I also can’t tell if some of it is in my head and I’m seeing or hearing him as more irritated than he is. Our relationship has never been like this. We have always been relatively good at taking and dealing with things. But for some reason since I’ve been pregnant it’s all gone to hell and I don’t know what to do.
