<human>: Can you provide a brief overview of the text?

I've broken up with my ex for three months now. A few weeks ago, she told me that she's pregnant. I don't have any proof that she isn't pregnant since she did miss her period after the break-up and she has never missed her periods when we were in a relationship. When I initiated the break-up I was not aware that she was pregnant. 

We've had an acrimonious break-up and when I asked her about her pregnancy, she refused to talk about it. Rather she spent most of the time berating me for breaking up with her. 

Since breaking up with my ex, I've gotten a new girlfriend. Should I tell her about the possibility that my ex may be pregnant? I don't want her to freak out over something that may not even be true.
<bot>: I'm not sure if my ex is pregnant with my child. Is it wrong to hide this to future relationship partners?
