My period is usually about 32 days long. My last period started on march 9. Then I haven't had a period since then. Instead, I have been getting ovulation signs every 2 weeks. So two weeks after my period I had the egg white like discharge I usually get when ovulating. Two weeks after this I got the discharge again, and another two weeks after this had the discharge again. No sign of my period. I am 28, overweight and I am not pregnant. what could be wrong with me?
