Hi there, My period ended a week ago and over the past few days i have been spotting for some reason, which is very abnormal for me. My period started off light then was semi-heavy and then brown blood for 4 days until it ended. I am also extremely moody this week, have headaches, mild cramping and slightly tender breasts. I am on the progesterone only contraception pills and have been for 3 months now almost. Also, early last month i took the morning after pill, but it has never affected me the previous time i have taken it. Do you think I could be pregnant? Spotting is abnormal, and I'm not sure if its implantation bleeding, and whether or not my period was actually my period :/ Thanks
