4dpo cramping

* I KNOW WAYYY TO EARLY TO TELL BUT I NEED YOUR EXPERIENCES OR THOUGHTS*

today I am 4dpo and I started cramping on my right side. I took an OPK and had a positive on August 3rd and 4th. My OB told me to count the 4th as my ovulation day.

I am kind of hopeful this month because I had an HSG done on 7/19 and my obgyn said to really try and BD for the next 3 months as the HSG increases your chances ??

Anyone on the same boat with the HSG and cramping?
