20 days late not pregnant

Em

According to this app, my period is 20 days late as of today.

I used a pregnancy test on the 5th day and it came out negative. I also used one 17 days late and it was negative again.

My bf and I are not trying to conceive, and we’ve been using condoms and being safe.

I have no idea why my period is this late, it’s always been regular for the last 15 years.. I’m not stressed out or anything either and my days have been roughly the same.

Are there things that can effect your period and make it late like this?

Is there something I can do to get it to come?

My hormones have been making me psycho because it’s so late!

Ugh I need help! 😭
