No labido, husband feels like intimacy is gone..

My husband and I have been married for 5 years. We have always been very close and have had a great relationship. We struggled with getting pregnant and having 3 miscarriages in 1 year. It definitely affected our relationship and our sex life. We finally got pregnant and are 35 weeks. I have not had much of a sex drive (I think I'm subconsciously fearful itll cause me to lose my baby, but I really dont know). However, at this point, sex is so uncomfortable. Last time we had sex about a week ago, I started bleeding and having contractions. my dr told me no more sex until 36 weeks. I had an emotionally rough day yesterday. I was in a funk and could not seem to get happy. My husband said he wanted a blow job because I cant have sex. I told him I really was not in the mood and wanted to just cuddle and talk. He got quite upset and went on a rant. he said he feels like we are just roommates now and the intimacy in our marriage is gone. I'm so lost about what to do.. there have been multiple times where he wanted sex and I honestly didnt, but I did it anyway to make him feel better. He was complaining about that because he said he could tell I was just doing it to please him. Was I wrong for having sex even though I didnt want it? He is not understanding that my hormones are all over the place and I dont really have control over much. Any advice? I know this message isnt very organized and kind of all over the place. Hopefully someone can follow it and help a sister out!
