Hot body but no fever... ?? Advice please

Jessi
So the past few days I've noticed my body feels hot, hot enough that my SO noticed this morning and asked if I felt ok, which i feel fine like i dont have a fever just really warm. I've frequently had headaches which I hardly ever did get those, I was cramping on my left side for the last 2 days but I'm not supposed to see AF for another 2wks. (September 14th) According to glow I ovulate this week. I have a 37-41 CD. What's ur thoughts on what I'm feeling? Or has anyone experienced this before getting a bfp? Ttc #1, first month on reproductive vitamins and using pre-seed. Going crazy here! :-)
