Advice/Opinions wanted

So, I’m a part of the not trying, not preventing group.

My period is super on time, has been for years, no matter what state of mind I was in it was always on time, so I was at my doctors 2 days after it was due and she made me pee in a cup and the test was negative, but it’s been a week and still no period.

I’ve been feeling really sick and apparently I’m not with it and look pale all the time.

So I’ve got no idea if I could possibly be pregnant, should I buy a test and try it? Or wait a while?

Also I’m not getting any of my usual pms symptoms, so I’m totally not like I usually am before my period and I don’t know if I could possibly be pregnant or just sick lol.

Any suggestions?
