Period hormones or pregnant?

LMP before it stopped: Oct 20-24

Last time I had sex: 1/19

LMP: 1/20-1/25

Throwing up: 2/10 and 2/16

Nauseas: 2/10-current

I had high thyroid levels and my periods were very light until they ended in October. I did have hormone panels ran, and I was still ovulating like normal but with no blood period. January I had my period, but it was spotty the first day and a lot lighter than it usually is (I only needed a panty liner).

I’m not on birth control, and have only had sex one day (multiple times that day).

I’m getting nauseous with everything I eat or drink... saltines, regular food, ice chips, Gatorade, ect.

I’m alway way more emotional than usual, getting teary eyed at every little thing. My next expected period is in 5 days.

Should I be concerned and take a pregnancy text or is this normal for a body trying to adjust to the period hormones again?
