Help. This isn't just period cramps!!!

So the pain started 7/26. I got the sharp pain that went from my right ovary to my sphincter while having sex. It was so bad it inhibited sex and made it impossible to just sit down, I had to sit on my hips for the rest of the day. I just thought it was period pain because I was do to start (started exactly a week later on 8/2). Anyway the pain would come in flashes throughout my period, and with each time the pain was worse. To the point on 8/5 I was actually crying but then had to force myself to stop because with the heaving breaths the pain would get worse. This was two days before my cycle finished. Oh and the pain didn't happen unless I was having sex or just finished pooping with few between those actions. But the pain stopped after the crying episode and didn't come back I thought it stopped because I switched to the diva cup (I heard it helped with cycle length and cramps). But anyways fast forward to today while I was working out (doing bench press) I got the sharp pain again! It was more of a stabbing feeling but in the SAME LOCATIONS!! It only lasted a second but still. So now I'm scared IDK what it is or could be but I'm calling to make an appointment with a doctor tomorrow. But I'm really scared and afraid and I just don't know what to do.

Does anyone have any thoughts or suggestions as to what this could be?

I'm hoping for the best but expecting the worse.

Oh I'm on nexplanon and my cycle was shorter than normal (hopefully the diva cup did work with that) and I started the diva cup the day after the crying episode. If that helps. Sorry this is so long but again I'm scared. Please help.
