How soon can I test?

K

My last period was July 22 - 27. We had unprotected sex on July 28, July 31st.

According to my tracker I was fertile during august 7-13.

Also had unprotected sex August 1,3, 8,9,10.

This whole past week I’ve had more intense cramping, which I’m not sure is ovulating or not?

How long should I wait to test? And yes I know if I did get pregnant during the August period of my fertile time I’d still have to wait a few weeks. My cycles are between 35-38+ sometimes. Lately averaging at 35.

I’m just curious if maybe I could have ovulated earlier than my app said...
