Anyone discovered they were pregnant but thought AF was coming?

So tonight I have got serious AF symptoms, like every time I go to the bathroom I expect to see she’s arrived but nothing yet. I just have usual wishy washy feeling in my tummy and feel exactly like I do a few hours before she shows her face. Although she would be greeting me 3 days earlier than expected but hey ho. Anyone ever felt this but discovered they were actually pregnant?

I know I’m clutching at straws here but there’s always hope right until AF shows 😉
