Opk & ewcm help

Brianna

So I had a 100% positive opk just 1 week after my period start date. which seemed awful early, but I just went with it. Well here I am 3 weeks after my period start date and I have a lot of ewcm this morning. I know once you get the positive opk you stop taking them, but I took one because of the ewcm and it was positive.

This is more in line with the time I usually ovulate. Is it possible the first opk wasn’t correct?
