Ovcon and stomache

I have been on ovcon 35 for 2.5 months, the first month, i had my period for almost 3 weeks straight, doc said this is normal. HHHMMMM??? Crazy break outs on my chin that have still yet cleared up. Second month, I had a weird muscle spasm in my stomache on the left-side below my ribcage and also what I thought was a pinched nerve in the back of my right thigh (couldn't walk, sit or bend for a couple days). Also, for the past couple months, this is crazy, but my teeth hurt so bad, they ache constantly. Not sure if this is due to this pill or not, but they have been hurting for as long as I've been on this pill. I have also gained a little weight. I think I have taken my last pill. Has anyone else had any of the same problems?
