Sorry to hear that Prama - I still have my fingers crossed for you - until AF arrives it ain't over!!

Karen - you should check out the 'charting your cycle' thread as this is the sort of thing they discuss there. Indications of ovulation are increase in CM especially EWCM, an increase in temperature, a +ve on the OPK. Unfortunately the temp and OPK are indications that ovulation happened within the last 12-24 hrs so often can be too late. However saying that I ovulated on the 04 May and we only had unprotected sex on the 05 May so go figure!!!
