I take my BBT at home every day. I am at 8dpo and due for a period on Friday or Saturday. I have a 24 day cycle. But, my temps continue to say 97.79, 97.65, 97.70 throughout my cycle. It doesn't go up to 98.0 at all after ovulation. Is there a problem with me? Doesn't seem to rise after ovulation. Guess im not going to have a BFP again this month if its not going up. I do, however, keep a fan on me at bedtime all year round...even in the winter months. During the winter months, I just keep a couple of comforters on me, but i need that air on my face. Do you think its possible that the fan causes my temp to stay a bit lower than it should? I can feel AF coming! Im having PMS symptoms already. :( Im so sad.
