My periods have always been irregular. Usually I get a period 2 months in a row and then skip the 3rd month. Twice I had it where my periods have been 3 months in a row. I got married in June (I wasnt sexually active before that) and got my period that month (3rd month in a row) so I should not have gotten a period in July according to my chart. So when I started having a period in July I thought it was implantation period. The "period" was short (3 days instead of usual 4). I took a bunch of tests that all came out negative. So then I thought I definitely wont get a period in august since that would make it 5 months in a row that I am getting a period (which NEVER happens) . 2 days ago I noticed some light discharge that kept up for a couple hours and then clots started coming out with some blood. This continued through all yesterday and towards the evening it started to stop and there was barely anything there. The color of the blood/bloodclots was brown/blackish red. Today morning there was only a little bit to wipe (i already didnt wear a pad) but in the later afternoon all of a sudden a clot with blood came out and thats it. Now it stopped again. What is going on?? Is this implantation bleeding? Can someone please help?
