Crazy hormonal!!!

I'm super hormonal and I'm hating it. I've been fighting so much with my SO and I just feel so distant. I want to just break up but idk if it's just my hormones causing me to get upset over the smallest things. I just really can't stand him lately and I hate the thought of us being together. We've been together almost 7 years so I'm sure I would have known a long time ago if I didn't want to be with him and I didn't start feeling this way till I hit 10 weeks. Any advice? Please no rude comments, I'm just so stressed and idk what to do...
