My last couple of cycles have been a bit off, I was 28 days for months then suddenly 31 then 29, so I'm not 100% sure when to expect my period this month. I'm on CD13 and I've had ewcm since Sunday. I think I'll ovulate Friday but that's just my guess. My problem is my husband is away until late Saturday night. So I think I already know I'm out this month. I've just started bbt this month, from CD2. I'll attach my chart so far to see if anyone can work out when I may ov, although I know everyone is different x
