Thank you everyone for the advice and reassurances. I go to see my doctor tomorrow, but already I feel better about why this has been happening. I have tried to eat healthier and back in April did start exercising more (since then that has stopped again). I'm thinking perhaps I tried to change too many things at once. I quit smoking and started eating a lot better than I was. I did lose a few pounds since then, but have also gained those back. Fortunately only those few have been gained back.
I was just starting to worry too much about this and was wanting to hear from others. That alone has made me feel so much better. I was on birth control at one point a few years ago, but since then haven't used it. I loved the Nuva Ring and I'm hoping to get back on that in the next month or two. Perhaps that will help.
Again thanks to everyone!
