I need some advice

My husband(of 3 years) has been ignoring me for almost a week now. I called him today, 3 times, before texting him to call me.

He picked up the 4the time and I told him that I missed him and I want to talk to him... he hung up in my face. It’s been 5 days!

I’m assuming he’s mad because I didn’t feel like giving head. I was in the room relaxing and he burst in wanting sex then eventually wanted head. I wasn’t into it because well... I’m not a light switch! I wanted to relax.

I’m also 12 weeks pregnant and ever gone we have sex my stomach cramps soo badly that I cry and think I’m about to have my 3rd miscarriage.

Is my marriage over or what? I feel broken
