Huge question to any girl who can answer it

So my boyfriend and I are trying to get pregnant. We start the day after my period ended so the 28th. When would be the right time to take a test??? We have been having sex ever since I finished my monthly. I’m just really impatient and really want to take a test, I just don’t want to see the disappointment.

I had a miscarriage two months ago, I was 8 weeks when I lost it so I know what I should feel when I do become pregnant again.

I also want to know when I can get pregnant again after a miscarriage???
