Should I be worried?

This is my first baby. I'm already high risk as I'm 35 with a history of infertility & an early twin miscarriage, plus I am diabetic. So every thing is new to me. I'm 26 weeks tomorrow with our baby girl & I've been feeling her movements all over the place for the last 2 weeks. Tonight I was soaking in a warm Epsom Salt bath with suddenly I started getting some aggressive kicks or punches right in the vagina. Like she was trying to break out. I quickly sat up & it stopped. It seems odd for her to be that low right now, especially when she was in my ribs yesterday. The internet gives mixed answers if some saying it's fine & some saying it's not. Has this happened to anyone else? Was everything OK?
