I have been with my partner for 2 years and I`m 17. I`m waiting for my period to come. I`m suppose to start somewhere this week of the month. ( First week of the month. & today Jan. 18) Not too long ago, I thought I was on my period but I wasn't. I thought I had vaginal brown discharged but then looked at it closely, it was sort of pinkish brown. Then a couple of days later, the pink gotten darker to red. I was bleeding with brown discharge for 2 days thinking it was probably my period but then stopped yesterday which was weird. I have been experiencing some a little craving for juice or sweets lately. I have also been feeling a little light head or headache here and there and plus a little nausea and a little tired during the day of wanting to sleep. So today when I got picked up from school, a headache just smashed into my head causing me to feel like throwing up. It happens every time my mom drives only though. I sometimes feel like I`m pregnant but wouldn't think so since me and my partner are always so careful (unprotected sex). I don't know how to explain more but I need help? Could I be or not? I haven't took a pregnancy test yet because I don't think I am.
