I have been on provera to start my period, then clomid to induce ovulation (I don't ovulate on my own). Today is day 11 of my cycle and I have a headache as well as a few small cramps this morning. I also discovered what looks to be the beginnings of a cold sore on my lip (I have never had a cold sore before, just canker sores). Are any of these indicators of ovulation? Is it too early to be ovulating. I have never had regular cycles so I don't know how long my cycles really are.
