How much time should I wait? 😥

Alejandra • 🇲🇽😍

Hey guys! This is weird for me cause I recently started to be sexually active. My boyfriend and I had sex on April 20, unfortunately we didn't protect ourselves and I was supposed to have my period 4 days later. I have 10 days of delay now, I'm very constant with my period and I'm checking my app all the time cause it's always accurate but this time I don't know what to do or if I should start panicking about it.

I read something about how stress can affect period so I'm telling myself that my delay is because of that, but I'm not really sure and I don't know if I should go to buy a pregnancy test now or should I wait a little longer?

Help!! 😥😥
