Just a quick note to say hi! I went through the same thing and came on my period and it was very heavy...with bad cramps, started to notice dark brown clots. My period went on for a week though. I suggest a blood test, I had gone through at least 6 catons of test and all showed not preganat. I was disapointed and scared. You are not alone and wish you luck xoxo
