CD 35 Still no AF; 4 BFNs 😧

Chasity • Since I was small, being a mom was the 1 thing I knew God had for me... Still trying to figure out the rest TTC #1
So my husband and I are not actively TTC. We are still relatively newly weds. My LMP was February 13. Not sure when I ovulated. I have very regular periods, average 27 days. AF is 6 days tardy to the party...what do you guys think? How long Should I wait before testing again? 3 were FRER and the other test was Clear Blue Digital
