Femcon FE Ovarian Cyst, Second Thought, Birth Control, Cuz, Prescription

wow!, I was just given a prescription of Femcon FE, an now I am just wait to start it but after reading all this I am having second thought. Though I am 21 and have never been on Birth Control, I have a ovarian cyst that hasn't went away since June. And I cannot do anything when I get my period due to the cyst. So I had to see a specialist and he told me to take Femcon, I am totally against BC because I don't think its right to Mess with your flow..but this is the only way to get it out with out surgery!...now I have already gain 10lbs from my cyst and went from a 34smallB to a 34LgC almost a D...so I really hope they don't get bigger...he also said that this was the lease hormonal drug thats why he gave it to me? is that true?
