I understand that when you ovulate your Basal body temperature rises..I'm not really sure what Basal body temp is, and if this temperature spike is something we can feel without taking temp with a Basal thermometer., Like a hot flash,or something..I also heard once this temp spikes and if you do concieve it stays elevated...I have felt cold for a week now..during ovulation and now, does that indicate that I'm probably not pregnant because i don't feel warm..Sorry if that sounds completely stupid, can anyone explain Basal body temperature to me?
