Depressed or just hormones?!

A lot has been going on with the father of my kids lately. Basically him talking to girls still after I told him I was pregnant, and him talking down on me to his friends in text message. When we found out we decided to get back together and he moved back in. Well he was still talking to those girls and I found out and of course got upset and told him to leave and he wouldn't. Well then in the phone to his friends he said "she got my talking to a bunch of girls and she still being necia lol"  and saying that idk why I trip out on him if I should be the one that's glad he's still around. When I brought it up to him he said it's just guy talk then bitched at me for going through the messages. So it's basically stuff like that, that I'm going through with him. Just two days ago I had a threatened miscarriage. Was bleeding very bad.. So like today, I don't feel myself. I'm not happy at all. I'm not happy with him. Idk if I'm depressed or if it's just my hormones. And I don't wanna feel this way becUse it's not healthy for the growing baby.... Ughhhh I just wanna feel myself and be happy again.
