I recently asked the question if I was pregnant because the month of Jan had been strange in terms of my intake of birth control (which I have been regular on). I had regular periods from Jan 4-11th, I took the pill on the 12th, but missed it from the 13th to 17th but took it from the 18th onwards and have been daily taking it till now. I was sexually active on Jan 25/26th and I did a pregnancy test, which was negative. I am still have an onset of period bleeding though. I am still continuing to take my regular regiment of the white pill as I will be with my bf from the 12th to the 22nd of Feb and I want to remain protected. When I went to the bathroom, I saw bits and pieces of the uterus lining too just now but very minute fragments. Any suggestions why my periods are being this way? If so, how long will they last? They usually last 4 days on a normal cycle but its surprising that they are still happening even though I have been on the active pill since the 18th Jan.
