What dpo do y’all start testing?

Just curious it’s my first month on Clomid I go in for blood work on Saturday to see if I ovulated. So if they’re testing my progesterone 6 dpo can they tell if we’re pregnant or is that too soon? And also when do y’all start taking pregnancy test? I’m someone who loves to pee on a stick too much 😂

(I’ve been trying to conceive for over a year and lost my son due to his umbilical cord being wrapped around his neck but I just had horrible side effects with Clomid so I’m really hoping it works and I’m antsy)
