irregular

hi,
well let me get right in to it as the title sugessts yes I am 20 years old and yes i am a virgin. well this thread is not about sex but about the fact that although i have always been irregular, for the last 2 years my period has been particularly distant. last year after about 8 months of not having a normal period but having had all the symtoms of PMS (bloating, cramps, headache, ext.) I was forced to enduce my period. I used a great herbal remedy by the name of humpfrey's #11 tables that are natural and side effect free. they fixed me right up for a while. This year how ever i have been expiriancing the same dry PMS like symtoms, only i get a very heavy yellowish discharge sometimes with a little clotting in it that looks like a pale colorless menstral. It took almost 2 weeks to turn in to a regular period that only lasted a day, went away, then came back a week later, and lasted one more day before disapeering for good and leaving behined that same discharge that is slowly lessening....I tried the same remedy and it dose not seem to be working maybe they changed the formulation (the label was slightly different)....So my questions are does anyone know what could be wrong with me???? Has anyone expirianced something similar??? What should i do to fix this problem????? HELP!!!!!PLEASE:conf used:
