Oh that is too funny ! what a classic ! so you were not even trying/ expecting it ...
Yeah! We were lazily trying (just not bothering with protection the times we DTD - which wasn't often in those few weeks) but not really expecting much to happen Because my cycles have been all wonky the past six years or so, I had no idea if I was due for AF or not. Turned out I tested around 14DPO anyway, lucky me

If that'd been a false negative, or a less sensitive test, I reckon I wouldn't have known for at least another month and a half - it was a month before our wedding, so I would've just put the lack of AF down to stress and the aforementioned wonky cycles
