Hi, the same thing is happening to me but I had protected sex Aug 20th and had a normal period from Sept. 1st - sept. 7th .  I started spotting on the 16th of September and is still spotting up until this point (September 23rd). This has never happened to me before. I masturbated the day before i started spotting so i contributed the spotting to the fact that maybe i cut myself BUT i am still spotting :-( .The suspense is killing me.. is there a possibility i can be pregnant? Oh and the spotting is very light, i know its not a period and its dark brown. Sometimes when i wipe after i urinate however, it is red. In addition, i have been having some sharp cramps in my lower abdomen, its off and on but the cramps eased up. So please.. Could i be pregnant? If not then what is wrong with me?
