Im concerned and a bit worried. We have been trying for just one month, from the day I think I ovulated Ive had very sore breasts, back ache(which is rare for me during my normal periods) and just havent felt myself. My period is due on Thursday. I woke early hours this morning to bad cramps and pain that went on for about 3-4 hours and it has been on and off all day but not as strong. I then noticed brown stains in my underwear. Everytime i go to the toilet there is bright red blood but nothing more in my underwear. I think this is just my period but its nothing like my normal periods, Ive never been early, and usually start heavily bleeding before I get the cramps. This time it seems to have been the opposite, pain first and then slight bleeding until i go to the toilet when a lot comes out and is bright red. Like I said I dont think it is implantation bleeding, from reading everyone elses posts but im worried that im showing signs of pregnancy and it could be an ectopic pregnancy. Has anyone else experienced this type of bleeding and still been pregnant?
