Trying for baby no.1

hello, all.

I need some advice, I’m 4 days late for my period according to both apps. It’s never this late I’m pretty regular so my period is always on time. I did not track ovulation or tracked baby dancing so I have no idea if we were even in the window. I took a test yesterday and it was negative. I have tinder nipples and cramps on/off. Has anyone had this and gone on to be pregnant.
