I’m 32 weeks and having really bad mood swings. I get these periods of time where I am so tearful, I feel hopeless, like I want to break up with my partner and don’t want to be pregnant any more. It normally lasts about half an hour and then passes and I feel back to normal pretty much but it is really scary and makes me worry about getting post partum depression. Is this normal? Should I worry? It’s not constant, only intermittent, but when it happens it’s very intense and the thoughts feel real although it's not.
