For the past two weeks I've been spotting and cramping despite being on my birth control, I thought it was just my body readjusting to it because I had to take a month off of it in August. I went to pee Sunday night and dark blood gushed out of me along with a big piece of tissue. I've had blood clots before but this is no blood clot. One side ends in a skinny thread, turns light skin pink and branches down and out into an oval shape that is dark red/pink. Since then I have had more but milder cramps, back pain and nausea.. I think I may have an a miscarriage with an unexpected pregnancy.. I called my doctor and the nurse just told me to come in on my appointment Thursday (coincidence that it was this week.) She didn't seem particularly concerned, and when I asked if I should bring the tissue in she said "yeah I guess you could." Should I be more concerned? Has anyone had this happen? I know if I did have a miscarriage that there is nothing that can be done now, but is it normal to be so nonchalant? Even if it was not a planned for thing?
