How early do you start testing?

Kenia

I’m 7DPO and IUI insemination and going stir crazy wanting to test but don’t because I don’t want to get a negative.

I’ve felt cramps and tightness but scared to be hopeful.

I even came up with the idea to pee in a cup and have my husband do the test and not tell me 🤦🏻‍♀️. I’m already trying to ask him what it says.
