My ex boyfriend and I had sex with no condoms but he would pull oout my periods super irregular and I was wondering there was anyway I was pregnant or if I'm just being paranoid...

Pull out is really not a method, it merely reduces sperm, does not stop it.
So of course you can be pregnant, You will just have to test to find out

Sure it's possible that you're pregnant. You are having unprotected sex... pulling out isn't a reliable method of birth control at all. So again, yes, you could be pregnant.

Are you actually pregnant? There is no way for me to know that.
