Hi everyone !
So ... my period is usually on time (27 days) with ovulation at the 13th day. But this month is really strange. I had second line on the opk at day 14th (06/07 not strong positive tho) but my bbt was low in the next 3 days. It went from 36.40 to 36.05 and 36.15. I thought that this month will be anovulatory and stopped measuring bbt. This was until 21st day of the cycle (13/07) when bbt was again 36.40. I made ovulation test - strongly negative. The next measure of bbt 27th day of cycle (19/07) bbt high 36.97 and it's like this until today 37th day (29/07). I made pregnancy test a week ago, but it was negative. Tried this morning again but it gave me an error. I was wondering if someone can help me with the calculations when my ovulation was. I know my graph is not full but any assumptions will be still helpful. I decided to wait until Sunday and to go to doctor afterwards if af doesn't show but until then if someone can give me an advice I will be very grateful. I was wondering also if it is possible that af skips this month even with the high bbt. Thank you in advance everyone
