NEEDED ADVICE ASAP

Me and my boyfriend were just fooling a bit, and we began to have sex but not enough for him to cum, so only a bit of precum went inside.

A few days later I started feeling like crap, and I googled it and it said you could get pregnant from precum, the next morning I took a text, and it said negative, so I was ok for about a week after that

It gets to the day of my period, and it doesn’t show. I panic and get all scared and uoset, two days after my period passed I take a test and it still said negative.

It’s now been about a week since my period should have been. Should I be worried or panicking, I am 16, and I have always had an irregular period, sometimes I’ll miss it for ages and sometimes not.

I would just like to hear from some other females if I will be ok or not to boost my confidence or to know what to do

HELP PLEASE
