hey so my menstruation just ended and while it was here everything was a little on track. Usually I get cramps for the first day of my menstrual but the cramps came every other day and my menstruation was even a little shorter that usual. I took a plan B in like the second week of March and My period came 2 days late and I had a little incident where I thought I had got pregnant but my period came and this incident was after I took the plan B in the second week of march. Now my period is over and im getting menstruation symptoms all over again but it doesn't feel like normal symptoms. For example my back hurts really bad and the right-side of my stomach gets weird pains in them and ii get weird cramps in my stomach around my bellybutton and below it and sometimes it feels like gas and other times its this really really weird feeling and that feeling only comes around when im laying down and this really blocks my sleeping. Does anybody has any suggestions of what might the problem may be? I was thinking appendicitis at first but now idk
