PCOS and normal body temperature

Kristyn • 35 with PCOS and TTC my first since 2008. Miscarriges 4/14 & 7/15 hoping for a rainbow baby .
So as some of you know with PCOS we tend to have lower body tempatures. Does any one know if a raised normal body temperature could be a sign of ovulation? all my life my body temp has been around 96.8 until I started taking Vitex. I've been temping at night while lounging and watching TV just to see if there was a change. I've slowly gone up to 98.2.
