Ovulation

My husband and I are ttc and I have been following this app. I have been off the pill for two m I nths and have had two periods, also when im not on the pill my skin seems to go haywire and I get breakouts which has happend. I took my temp and for most of the month my temp was 36.7ºc on thursday when the app said I was ovulating my temp was 37.00ºc does this mean I did ovulate then? My temp is ba k to 36.7 for the last two days.
