Pregnant?

Okay so I never get PMS symptoms.

Like seriously, ever.

So when I started feeling nauseous a few days ago I was very thrown off. I had a lower backache, and mild cramping (which I also never get) and my sense of smell is insane. I walked into the kitchen at work and gagged at the smell of the cooked eggs.

I had a lot of gas. TMI ik. And I also was kind of constipated.

I’m just really confused because I was told you couldn’t have symptoms like this till after your missed period.

What I’m wondering is is it possible that I could be pregnant? And that these symptoms are that?
