When would b the best time to take pregnancy test if trying to conceive .. i ovulated around 4/6-4/8 had sex both days ..

3 weeks after...: A urine pregnancy test, when done correctly, will give a reliable result 3 weeks after sex.

When you miss menses: Over the counter pregnancy tests can usually detect HCG (pregnancy hormone) about 2 weeks after you ovulate or when you have missed a menstrual period. So, if you are right about your ovulation date, you should be able to test this weekend. Good luck!
