Isn't this horrible?

Backstory: So there's a chance I could be pregnant. At first, I didn't think I'd want the baby if I was because my boyfriend and I had broken up because we didn't feel the spark anymore. But I decided it wasn't an option for me to consider abortion so I'll be happy if I am pregnant or if I'm not. Here's the horrible part... My best friend, who knows all of the stuff I just said, and I went swimming yesterday. We were having a blast just jumping around acting like kids... Until she pulled me towards her and then kicked me in the stomach... Hard. I was initially in shock that she'd do something like that considering the possibility that I'm pregnant. I told her that it really hurt and that it was a stupid thing to do considering what's going on with me and you know what she said? "Well, I may have helped you!" And she laughed. I just shut down, my eyes got watery and I grabbed my stomach. She did apologize and said she didn't know why she said that, followed by a list of reasons I don't need to worry (like if I was pregnant I'd have to fall down the stairs to actually hurt the baby...) but still. I don't even know if I'm pregnant and honestly it hasn't been long enough since the sex for me to be pregnant already, so the odds that she hurt something in there are slim but I know that she emotionally hurt me. I now know that I wouldn't want her around me if I do get pregnant someday. Am I overreacting? Or would something like that upset you?
