Losing my mind? Or expecting the unexpected?

My period is 35 days late (LP 3rd Dec).

Since 3-ish weeks ago I’ve been constantly and I mean constantly nauseous every single day and even throwing up now and then. I can’t handle certain smells, I’ve completely gone off hot food too, I can only tolerate cold food except meat, I can’t stomach meat at all. I have tried to eat hot meals however I feel sick before I’m even half way through. I can’t drink anything fizzy either :( I’ve also got your usual symptoms, sore breasts etc.

I’m doing a test tomorrow so we shall see but what’s everyone’s opinions? How can I at least get myself to eat hot meals without throwing up?
