I went to the doctor, she didnt check me, just after hearing my prob, she said, since it happened to you the 5th day, it cant be implantation… She had no answer for my questions like, then if my reports are normal..y did I face that?? She was nil.. seemed to me not a doctor but an ordinary woman I am discussing my problem with, after seeing my reports, she even mentioned that I dont even have PCOS problem (for what I am glad), she said your blood report shows you dont have PCOS problem either… THEY WHY?? I asked, and she had no answer :(… According to implantation, my spotting has stopped on the third day… I will wait for more 5 days and will then have a preg test. My symptoms are as same as it should be if one is preggo!! Still I am neutral!! lets see!! If I get a positive test, id be more than glad, if not, will consult the doctor again!!
