Hormones?

Hey ladies,

I had my son July 2018 and I am currently 10 weeks pregnant. I also breastfeed my son. I'm always so agitated/moody and stressed out. I get so irritated with my 5 year old son and I hate that. Also I'm constantly thinking my boyfriend is cheating. It fills my every thought. It's ridiculous. Idk if this is all just from the crazy hormone fluctuations or if something else is going on. I'm going to talk to my doctor Thursday. Just would like some opinions. (pic of my sweet boys)
