Just as I thought I had a good day I asked someone if she was pregnant

So I thought I was having aa great day which never happens. I actually managed to get up and go out the door after 2 weeks. I started to feel good but then I spotted someone from my childhood and said hi  Then I spotted she had a bit of  a belly. I kept thinking don't ask but then I couldn't help it I just had to blurt it out. Are you pregnant to which she replied no am just fat. Now I feel so horrible and I just don't want to go out again. This is why I stay in. I don't know what to do I'm such a failure nd horrible person to even ask that.
