I wouldn't be surprised if you take 100 women, you'll get 100 different responses.
Two different gynos told me it could take up to a year for the effects of the synthetics to get out of my system completely and unless I was basically hemmorhaging, not to worry
My experience wasn't bad at all going off. I'd been on the pill for 20 years, didn't even remember what the real "me" was. I had zero libido, headaches, horrible periods, moody, weight gain. For me, the libido slowly returned after a couple weeks off the pill; now it's raging strong. The horrible periods were replaced with mild, normal periods immediately (Pamprin for cramps -- goodbye!!!). I've had a few headaches here and there, but nothing like the kind I had on the pill. Moodiness was gone immediately, as well, especially the PMS. As for weight, I think I lost all my pill weight in my boobs, LOL. The rest I'll have to actually work on losing
BTW, I went off the pill in early March of this year. I'd been on various pills over the years.
On the down side, my doc found what he believes are endometrial cysts on ultrasound. He believes the pill controls these and keeps them at bay; that my going off the pill probably had something to do with them. I have no pain with the cysts, but if they're still there in January (after finding them in April/May), they'll need to come out. He did offer me three months of BC pills to try and shrink them, and I said no way, never again. I'll take my chances with a lap and two to seven days of recovery instead of three months on the pill again.
Sooo, that's been the good and the bad for me. All in all, I'm really glad I finally stopped. I hope you find some resolution for yourself soon!
