What do

I get periods every other week.. 1 week on n 1 week off they've been like this religiously for the last 5 months , I'm now over a week late n experiencing a lot of period like cramps on n off ..very sore boobs n nausea that's been happening for almost 2 weeks -.-

I have had unprotected sex quite a bit but didn't think nothing would happen cz of my periods were irregular should I test or wait another week n see if my periods come?

Any advice would be great btw I am not ttc.
