I normally have 31 day cycles, this is my third round of Femara taken on 21-25 October and am now in my TWW. My last cycle was a lot shorter it was a 26 day cycle and for the first time I had fertile CM🥳 we BD every day around my ovulation period but according to Glow I’m only due for my period on 19th November. I’m currently on CD 28, I’m very confused and not sure where or when to track my cycle? I went from 31 to 26 day cycles? But now am currently on CD 28 with no sign of AF? Do I take a test now or should I wait until my ‘normal’ cycle would start on 19th November? This is also the first month I’ve started Metformin 1000mg once a day, but I it started it around CD 10, would that alter my cycle at all? Have mild cramps, lower back pain, extremity sore breasts but these could also be usual PMS symptoms🤦‍♀️

Secretly hoping I am pregnant as it’s my birthday on the 19th so that will be the best birthday present if it is a BFP!! Please help with advice I would so appreciate it! 🙏
