I am in need of advice. On December 12th, 2016, I was diagnosed with PCOS (Polycystic Ovarian Syndrome), which is when my doctor prescribed me with BC. I started out taking progesterone pills to initiate a period (I have never had a normal/regular period), and then as instructed, began taking my birth control on the second day of my birth control. So I am almost at the end of my first pack, and I am still on my period. My boobs are always sore, and I have nonstop cramps. I'm not sure if this is normal or what. My doctor didn't forewarn me of these side effects, and I did read through the side effects, but dang!! I feel terrible!
