is it possible for you to get a temperature shift, ovulate and then go back to normal temps pre ovulation???

basically looking at my charts i seem to have a really high temp for 1 or 2 days and then it goes back to normal and then af arives 2 weeks later.

this happened again on cd31 on this cycle.....but af hasn't arived.

I always thought i didn't ov, but could it be that the temp shift shows different in some people or am i grasping at straws???

Help?? Any ideas??

do u chart on fertilityfriend? what do they say? any chance u could list ur temps for a looksee? do u have any other signs of OV ie cm, opks etc? if ur temp goes down to pre OV temps after a couple of days i would say u didn't OV. pm me ur temps if u want
