I have endometriosis and have recently started trying for a baby (slowly as most of you know sex can be difficult!) . I have been feeling tired, having bouts of nausea, back pain and hot flushes which led me to think I'm pregnant! But I've done 2 tests both negative. I was due for my period 2 days ago and today have started spotting pinky/reddish blood but still not started my period. All these symptoms point to pregnancy as far I can find on the Web! Does anyone have any advice on what it could be?
