BFN followed by BFP???? Please help!

Dominique
Hello ladies, has anyone received a BFN followed by a BFP a few days later? I took a test this morning on a FRER and got a BFN 😔 I ovulated either the 12th or 13th and my AF is due the 26th. I am going to retest on Saturday I'm PRAYING I get my BFP 😩😩
