Weird Period! Anyone else?

Ho

Hi yall

So usually when it comes to my period, I get cramps, back pain, my stomach bloats and, my breasts usually are sore. I have hypothyroidism and my doctor changed the brand of my meds. Which leads me to be concerned because I feel fatigued, havent been bloated, instead I am just naucious morning and evening for a day and a half. I'm supposed to start my period tomorrow or close to it. Anyone else experience this?
