I got a positive ovulation test on thurs early afternoon (peak fertility) which was day 13 of my cycle - I was using the 4 day window tests but not getting any high fertility results (just went straight from negative the previous 2 days to peak) so I thought this means I would ovulate on the Friday, however on Friday morning my basal body temperature showed increase which I think may mean I had already ovulated by Friday morning? Does this mean I must have ovulated the day of the peak fertility test?
thanks :)
