My periods are pretty regular, 33 day cycles. With 3-4 days of actually bleeding. Usually normal flow, rarely heavy. My last period was February 29th - March 3rd, normal flow and everything.
My fiance and I are trying to get pregnant and had unprotected sex (no condom, no pull-out) March 11, 13, 21, 26 & 28th. I expected my period yesterday (March 29th); instead I had very light spotting on the 26th, light bleeding (only had to use 1 tampon the entire day, and nothing over night) on the 27th, nothing at all on the 28th, now yesterday and today I have a lot of dark brown discharge happening. I took a pregnancy test today as well, but that came out negative. Is it possible that I am pregnant, and this out of wack "period" is really implantation bleeding and I took a test too soon? Or am I just getting my hopes up and this is just a weird period.
