I am 37 years of age my past I have been pregnant 6 times and had 6 miscarrages.. had many tests done to find out why I miscarry so many times.. had a laperscopy done december 6/ 2006.. my diagnose was I have a bicornate uterus with no septum.. my last miscarrage was almost 2 years ago.. I get my periods every 28 days now my last period was the 4th of september today is the 16th of september.. I woke up this morning feeling differnt I experiece every ovulation day a sharp feeling on my right side and I have that feeling today which is the time of ovulation.. my concern is I also woke up spotting brownish color my next periods are not due till october 1st.. I dont know if I should go to the hospital and see what is going on because my next appointment with my gynocoligist isnt till the 19th of october and I am really concerned on this spotting.. I should correct above I have no kids just 6 miscarrages.. anyways should I go and see a dr at the hospital or wait it out? does this sound like implantaion I dont have to use a pad its only a little bit.. anyways I need some input on all this.. has anyone experienced this? and found out they were or are pregnant? please get back to me.. thanx..
