So im 14 year old girl and have recently been feeling movements and slight pains in my stomach. I am 99% sure I'm not pregnant as I have never "done it" before and I haven't even had a boyfriend yet. I also am feeling vibrations like my tummy is growling but I'm not hungry when this happens. I have been having trouble going to the bathroom to lately (sorry I had to mention it). Please let me know if you know what this is? Also sorry if I'm posting in the wrong category I'm just worried
