I'm going mad!! I need advice!!

I'm about 13 weeks pregnant now, I suffered from depression but I had to stop my pills as soon as I found out I was pregnant. Recently I've been getting angry over the tiniest things e.g. Someone's reaction to what I might be telling them. I'm talking rubbish and I get angry about what I'm talking about.

I cry so much now, I don't want to do anything, I cry over things my partner says like "do you want to go out" and I don't want to go I'll cry over it.

Its worrying.
