Can it happen?

Fiancé and I have been TTC since November 2017, but as our wedding day 🤵🏻👰🏻 is approaching next year, we agreed that it’ll be best to put TTC on hold until after the wedding. Who needs that added stress?! So. Sex usually induces AF for me. I’m 22 DPO. My question is.. would sex still induce AF if I’m already 22 DPO. 🤔 I had BFN yesterday, but I took it in the afternoon. I’m planning to do another one first thing tomorrow morning if AF doesn’t come. Trying to keep the test taking a secret from the fiancé, he got so bummed every time AF came when we’re TCC in the beginning. Don’t want to get him down again!
