Clomid again.

Hi ladies.

We are looking g at starting Clomid on days 3-7, I do ovulate on my own however we aren't getting pregnant, the thing is we are a same sex couple and rely on donor sperm that's not through a clinic. So timing needs to be perfect which we are getting right at the moment but my concerns are OPKs are all over the place when on Clomid so how am I meant to know when my true positive is? Help please

Ps we are unmonitored for the time being. After 3 months I will be monitored
