I was diagnosed with PID a week ago after visiting the gyn with symptoms of pain, particularly on the left side of my pelvic region, spotting, nausea, and feeling of heaviness and bloating. Since they gave me a ton of antibiotics, the pain has decreased but the spotting hasn't stopped and I have started to pass tissue. The blood has been very dark mainly but now I'm having bright colored blood too. I missed one pill this month and one last month and have had otherwise unprotected sex. I took a store bought pregnancy test a week and a half ago that came back negative but it would have been super super early. I did not miss my period last month. Should I be worried about the tissue? Is that just a side effect of PID?
