So sorry, EverythingXed and TaeBo! Hugs, I know it's rough.
Things aren't looking too good for me either. Long story short, I've been having some weird abdominal and back pain for almost two weeks, since before I even O'ed. At first I thought it might be O pain, then I convinced myself it was muscular. It got bad Monday night so I went to the doctor on Tuesday. When she pushed on my stomach, it was pretty clear it's not muscular. As soon as I told her we were TTC, she immediately thought it might be ectopic (although I think that's pretty unlikely, since the pain started before I even O'd). She also mentioned it could be my gall bladder or an ovarian cyst. So anyway, she did blood tests on Tuesday, including a pregnancy test, which was a BFN - again, probably too early to even show on a blood test, since I may not even have implanted by then, but it was still discouraging. Going back for more tests today and she may order an ultrasound. So...even if I could have gotten pregnant this month it's not looking good as there's clearly something else going on that's probably not making it very hospitable for a bean. And even if a bean could take hold, I may need some treatment for whatever is the problem, which probably won't be pregnancy-friendly.
Sorry for all the info, but feeling the need for a place to air all this out. DH is the only one who knows we're trying, and I'm having all sorts of anxiety about what's going on, so I need a place to vent!
