Help, I’m 11 days late!!

I am 11 days late. I’ve had most symptoms for getting my period, cramping, sore boobs, very tired.....

I’m on my 11 day and I’ve started feeling nauseous for two days now.

I didn’t want to believe I wasn’t going to get my period but I honestly don’t think I am and now I think I’m pregnant!

I haven’t been on BC in years. We never use protection anymore and he does the pull out method.

Do I wait a few more days or just go do a test?
