Friday I started bleeding a little and the next day it was a bit heavier. Any food I try to eat I seem to have no interest in, it doesn't disgust me I just don't feel the need to eat. I usually have that gurgle feeling of hunger when I wake up but not since this has started. I have had sex with my boyfriend but we ALWAYS use a condom and it doesn't seem to have ripped cause nothing is ever leaking from the tip where I can see his stuff has collected after he orgasms. As to the tired thing, I can sleep a full night and not be woken up or anything its just that i dont feel tired to go to bed at night. My period is just about over now. SO i don't know what to think about any of this. I'm 20 years old.My periods are irregular but THEYVE BEEN LIKE THAT EVEN BEFORE I EVER HAD SEX. They usually follow a three month pattern. I have my period then it doesn't happen again for three months and so on. Every time i have sex it is PROTECTED. We ALWAYS ALWAYS ALWAYS wear a condom. My periods are usually normal before this. My usual periods I get cramps but I dont get headaches or anything else. I have stopped drinking soda the end of May and have started exercising since the beginning if July.
