Jessi, i know how frustrating it can get when your body gives mixed signals. About 5 months ago, i had high temps that lasted about 6wks. I think i had an early m/c, but my body just didn't have a clue. Anyway, 2 tidbits of info:
1) Some women get preg, but NEVER get a +HPT, they need a beta HCG.
2) A lot of women have what seems like their period, possibly more than just 1, but are still prg.
So, perhaps give it a few more days. If your temps still don't come down to what seems the norm for you, get a blood test done. Make sure that it is a
Beta HCG (quantitative blood test, not qualitative). The other one is only as good as most home tests.
Good luck!
