False positive opk?

El

So the 14th i had my surge according to opk+. We bd the 10th 11th 13th 14th and 15th.

This is our first month trying and I’m alway very very very very very regular since I got my period at 10 years old. I have a 29 days period.

Usually I have a lot of ewcm when I ovulate and for some reason this time it was just watery very watery but I read it was fertile too so I didn’t worry. The 15th my husband left for work and I was sure we did a good job. I woke up today 2 dpo feeling wet down there and I have lot of ewcm like a lot. I can feel it coming down. And my bbt still very high.

I’m I ovulating late? I’m so sad right now because he is out of town. I always tracked my period and ovulation because we never used birth control we just avoided sex during my fertile window. So for me this is a first. Also never had problem with pms. Before my period I get no cravings, no cramps and no nausea. Now I have cramp and nausea. Wondering if I am ovulating late. Sorry I know it’s long. I just need answers. I kinda feel we are out for this month.
