The longest it took to get a BFP

What’s the latest it took you to get a positive? I’m 21 daysPO 6 days late for my period no positive test with my first I knew I was pregnant and found out at 6weeks. I dontknow if it’s just a late period since all mine are usually irregular but they were finally getting one track. Lemme know your struggle to get your positive test!? I need hope it’s been 14 months of ttc my period track just to show you guys it may be late or I am hopefully pregnant. November I was givin a pill by my doctor to force my period to start since it was a few months late no pregnancy and it started nov28th ended December 2nd then I got a normal period
