Sorry about your

I was certainly hoping for you. If it's frustrating you, I would call, if nothing more than to keep your own sanity. I know how up and down I was before AF finally turned it on full strength. Then of course I was sorry that she did, but at least I knew, LOL. No need in stressing yourself out more than is necessary. At least that way you will have some answers and if you are truely not pg then I think they would probably give you something to bring on your period.
Hope this helps and that you find answers soon,
