I have been charting so I can get an estimation of how my cycle works (I have PCOS and irregular AF...my last cycle was over 40 days). From all the signs I was sure O was approaching...then I got a cold. My temp went up and has mostly stayed up for the last 3 days, but all my OPKs have been negative (been testing twice a day for the last 5 days or so, once a day before that). The only thing indicating O has occurred is my temps...so I'm wondering if I already O'd and FF is right, or if my temp is up because I have a cold. Has anyone had experience with charting and getting a cold? Thanks!!!
