TTC and ebf

Any ladies here TTC? Ebf, think I had one period that lasted 3 days 2months PP (not sure).

So now, nearly positive opk, cervical position is high soft, closed, yellow tinge discharge. I got either a vvvvfl or evap.

Just wondering if any other ladies are checking their cervical position or doing opks whilst breastfeeding and TCC what they found?
