Hi. I have had a regular period and 28 day cycle since I started having my period. I am also sexually active. On the exact day I that I was going to have my period I had my normal cramps but no period. Exactly one week later I started having light spotting. I have not had cramps, fatigue, headaches, sore breasts, or anything irregular. My partner and I use condoms with Spermacide as our contraceptive. Within this last cycle I have changed jobs and moved. I am stressed out... Could this have something to do with my period being irregular? I have not taken a pregnancy test yet. Any help would be Greatly appreciated.

Thanks,
