When to test?

Rach

I’ve had a search round and found so many conflicting answers so thought I’d ask to make sure.

How many days dpo is it best to wait before doing a pregnancy test? Or is it best to wait till the day my period (hopefully only) should start - fingers crossed it doesn’t 🤞 or a week after when it should start - obviously if no blood/clots appear 🤞🤞
