Should I take a test?

Brianna

Lately I’ve been feeling very nauseous, tired, getting bad headaches, breaking out with acne and having horrible moods swings and sweating a lot!. My last period was in September and it only lasted 3 days. I have PCOS so my periods are like non existent lol! I had sex last night and the night before and I took an ovulation test yesterday and it said I’m ovulating. Could these just be symptoms of ovulation or pregnancy? Please Help!!!
