It's the 1st of the month!

Esther Rose • We're Timothy and Esther Bush. We have a 5year old and a 2year old little girl, and are due with baby girl #3 in April 2019!!✨☄BABY DUST TO ALL!☄✨
So I missed my AF on the 22nd. The last test I took was on the 27th and it was a BFN. I really want to test and I do think I'm pregnant, but I don't want to see a BFN..
When do you think it would be okay to test again?
