I think we’ve missed our chance 🤦🏼‍♀️

My cycles are always 33-34 days and I either ovulate on cd 17,18 or 19. I am on cd 13 and just went to the toilet and out came the biggest amount of ewcm. I checked my cervix and it’s super high and open. I hardly ever have ewcm but if I do it’s only on ovulation day or the day after. I hadn’t been using opks as I usually don’t start poas until cd 14. We haven’t had any sex yet this cycle as I have been unwell for the past week. I did an opk just now but it was negative. It would be just my luck that I have a short cycle this month and I’ve missed my chance 😡
