Please Help!?

Kristin • Been married 8 yrs, actively TTC for 6 yrs. I have PCOS & insulin resistance and never ovulate. My cycles are 100+ days. We just finished our fourth round of clomid.
Today was day 10 of provera for me. My Dr didn't expect it till 1-2 weeks after. But I started spotting yesterday, very lightly. Today has been steady consistent spotting more red and heavy. But not necessary to wear a tampon. Of course my Dr is out for the holiday and I'm supposed to start clomid on day 3. I spoke with a different nurse in the office and she said count today as day 1 of my cycle. I'm just nervous to count it too early before my first round of clomid. Anyone have thoughts on what counts as day one? Tia!
