Aphy, I've been using an online temperature adjuster. I've read that it's not accurate, but I know waking up even just an hour early really skews my temps!!! Some women say that it didn't work for them, but it has appeared to be pretty accurate for me on the couple of days that I had to use it.
For example, I woke up at 3:15 this morning and took my temp and it was 96.45 (which is really low). I put it in the adjuster for my normal time and it upped it to 97.02. When I woke up again, it was about 30 minutes past my normal time, and I took it, and it was 97.12. So I would say my adjusted temp was relatively accurate!
As far as the low temps, there are lots of women who say that they have had low temps and still gotten a BFP! I hope so much for you that it will be the case!
