BFP on day of missed period?

Lauren🥀 Mum to baby C.j❤️Pregnant With Baby#2🤰🌈

So my period is due today and I normally spot the day before... but nothing! No cramps nothing! I did have cramps 12 before AF was due.. I’ve done some tests and all bfn😞 haven’t done a test for 4 days now.. when should I test? I’ve heard that First Response is the best and that you can test at any time if he day with pregnancy tests of that kind of brand..

did anyone test on the day of AF being due and got their BFP!? If so, what time of day did you test? Did you hold your wee in for a couple of hours or not?

HELP! Xx
