BBT evelation during pregnancy

Should your BBT stay elevated druing pregnancy. Mine was but now at 9 weeks it has went back to normal. This scares me that something could be wrong with the baby.

I'm at 8 weeks and mine is declining (slowly, not a plunge) and I'm looking for this info too. I have found that BBT is supposed to go back to pre-ovulatory 'normal' after the first trimester. Seems really early for me but perhaps its a very gradual progression. I have had no bleeding or cramping and still feel very pg (nausea, etc.) so i'm not too worried. You shouldn't be either if there are no other symptoms. I think we both could benefit by putting our BBT thermometers away!
