I had sex while coming off my last period on 13th November, a couple of weeks later I started getting lower back pain and went to the doctors about it he was asking me about being pregnant but I never did a test. A week before my period was due I started having back pain and bad cramps again, with blood, after the first initial lot of blood it calmed down but still had the pains, the blood then went very light and was pinky/brown. I then passed something and the bleeding stopped and then light pinky brown discharge again the day after. I've been to the doctor and she said she doesn't know what it is and we should just put it down as a question mark. Does anyone know by the look of the pictures what could of potentially happened. I have done 2 tests, 1 came back negative and then the second came back with 2 very faint lines so I'm unsure as to what is happening. The pains are still here & I keep feeling sick. Thank you
