Stopping Birth Control

I've been on birth control for about 7 years (first implanon, then the shot, finally the pill) I stopped taking the pill this past month and this is our first month TTC. I've noticed I've had a lot of "symptoms" I don't usually have, such as backache, headaches, cramps, acne, increased CM, bloating and heartburn. At first I really considered I might be pregnant, but at this point I'm 13 DPO and keep getting BFN. I know it's still a possibility until AF shows up (due Monday) but I've kinda come to terms that this isn't my month. Anyway I'm just wondering if anyone has experienced "new symptoms" they didn't usually have once stopping birth control after being on for years?
