i have posted quite a bit on here before, but i have been on femcon for now going on 10 months and i started bleeding a week before my period is due. my period is not supposed to start until June 2 or 3. i am just a little worried about why i might have started my period 1 week early and i am still bleeding and no sign of it stopping. i have cramps, heavy clotting bleeding, sorry for tmi! has anyone else experienced this and should i not worry too much about it? oh and i have had other terrible side effects like major mood swings, crying for no reason, depressed and down all the time. anyway, your input is much appreciated!
