I am 33 and I have been ttc for 3 months now. I have a 3 year old and after stopping bf I went on the pill because of endometriosis. Since coming off the pill ive been temping and have ovulated. This month I was 6 days late with temps staying elevated. On day 7 my temp dropped about 1 degree and I started spotting very lightly. The next day the bleeding increased but only nearly filling a pad in 24hrs. Then it started getting lighter. I've taken several pts and they are all negative. WHAt is going on? Should I be worried about mc or ectopic ?
