I am 29 years old and I dont always have a normal 28 day cycle. I had my periods on 8th Dec '08. And from 15-17 Dec I had unprotected sex with my boyfriend 4 times. A week since then I have been upset in my tummy, feeling tired, lot of mood swings, missed periods, some cramping, and I also sometimes feel some tenderness in my breasts. I have taken the EPT test atleast 5 times and it's all negative. I took the last test on 20th Jan with the first urine in the morning. Today (22nd Jan '09) I had some brown discharge and I'm not sure yet if this is my period or spotting. Is it possible to have spotting 5-6 weeks after having unprotected sex? If yes, when can I take the test to be more sure? I'm really worried since I am not employed at the moment and I have no medical insurance either.
