What should i do? Please help!

This ridiculous I know but I just want to know if it’s a good idea to take a pregnancy test before your missed period?

On the 8th I had unprotected sex and he pulled out came on my back and went in again and then came again on my back. And also on the 8th i was ovulating and I’m suppose to get my period on the 22nd but I’m always irregular and never comes on the exact day it’s suppose to.

Just wanted to know if I should wait before my missed period or do it now?

I ALREADY KNOW IF I DONT WANT TO GET PREGNANT I SHOULD USE A CONDOM OR BC WHATEVER. SO SAVE YOURSELF FROM COMMENTING THAT. Because I don’t care about those types of comments.

Thank you to the ladies who give advices and not judge.
