I don’t know what I’m doing wrong

JM • 28 started TTC #baby 1 June 2016. 2 and half years 🌟

Been ttc for 2 years.

I have regular 30-32 day cycle.

I have bd through my whole cycles,

I have bd at the start of my fertile window

I have bd at the end of my fertile window

I normally get positive opks on cd16-17.

So I bd CD 17-18-19-20

I GET EWCM, Like a lot of it.

Hmm I don’t know what I’m honestly doing wrong :( I don’t know. It’s just really upsetting. Anyone else in the same situation as me ?
