I am late by 10 days. I have taken 2 tests that both say I am not pregnant. I have two beautiful children already hence why I had my tubes tied and burned but, this month I did not get a period yet. My periods have never been normal and I was supposed to go to the OBGYN about possibly having endometriosis because my periods are bad. Last night after having sex, I started to get a sharp, throbbing, burning pain in my right side. I called my nurse and she said it’s a possible kidney stone (which I am know to have) but, I’m just not sure. Any suggestions on what it could mean? What should I do? Besides seeing an OBGYN?!!
