What should I do?

Because of my insane pregnancy hormones, I have been super uptight lately to where I'm pretty sure my SO is trying to avoid me. I think I've been selfish and talking about my feelings way too much and always trying to have serious discussions about everything .

I rationalize my behavior by telling myself we need these talks because I can't hold my thoughts in, but I'm realizing its excessive and my worrying is becoming stressful.

Right now I'm actually worried hes distancing himself and I dont want to have ANOTHER serious discussion about my behavior because that's just so much... but I also dont want to sound crazy by just turning around and being fake all of a sudden

I think I sound crazy right now, but can anyone slightly relate or give some kind of advice?

I have 3 months til the little guy is here and to be fair I've never been this hormonal in my life
