Hormones/low mood/pms?

I had an ectopic pregnancy removed on 22 January. My periods were irregular before so I don’t know when to expect it to come back. I have been coping and coming to terms with things well. The last week i have had extreme moods, irritable, angry, upset, crying, no tolerance with people. It’s like extreme pms symptoms. What’s going on with my hormones? Will I settle down again? Also when do people start trying again? I’m desperate for a baby. As is everyone else here xx
