Im 18 years old and I have started my period at the age of 12. I can't say my periods has ever been regular, about 4 months I would get them on dates that are located around the same area, then suddenly I would get it every 20 days for a few months, sometimes I would miss a month or two, etc. (The most regular it has ever gotten is at the most a year, then it went irregular again) I have never been sexually active (intercourse or anything involving an erection/sperm near my genitals -- I am a virgin). Recently though my periods has been at its worst state, since december, I have had my periods about 3-4 times. Right now, it's been about 3 months since the last period and I finally got them, however I really don't know if it's actually period because there is BARELY any blood or barely any pain (Usually when I get my period, I get a looooot of blood) Also, my period has always been around 7-8 days but the last few times I got my period it only lasted about 5 days. It always seem to lower in days. I'm really worried this could affect me having kids in the future? Lately I have been gaining weight and losing some weight on and off, I also have a very crappy mood (I might even have depression for all I know.) I don't think my diet is the cause here, I used to have my period even when I barely eat. Could anyone help me? I really hope this doesn't mean anything bad. :/
