Too late

So yesterday according to glow my ovulation was yesterday, I had EWCM last night but partner was sick in bed so nothing happened. We have only managed to have sex once this fertile period but today I have really watery CM and when googling it says that this is fertile CM and the more watery it is the closer to ovulation?

My cycles aren’t generally clock work and today I have sort of cramping is it a possibility I could be ovulating today?

I don’t get home until half 5 🙈 I know how precious and little time there in when TTC and ovulation....will I have missed my chance?

Don’t use OPKs as generally never seem to get a positive, we wanted to try a more relaxed approach. I thought I never ovulated as periods are pretty irregular and have PCOS but my CM has never been like this before!
