I'm new at this, just started checking my temp this cycle. I need help understanding. My temp was 97.1, then 96.9, then 97.6 (I had wore pajama pants that night so now I make sure I'm wearing the same thing as well as doing it at the same time), 97.1, then today 96.9. Is it supposed to fluctuate. I've had flashing smileys and one light lighter than the other on first response OPK. EWCM and watery for 4 days now. I'm scared I'm gonna miss the surge or have I? How could I if I'm still getting smileys?
