I know it's probable not likely, but...

I'm on mirena so that's already 'probably not pregnant' but... about 3 weeks ago I has my "period" it wasnt like any other one ive had since on this birth control- it was super short and light(usually last LEAST 2 weeks). And right after it ended I started waking up every morning nauseous and extremely tired all the time. But as of the last couple days it's been all day nauseous, nothing sounds good to eat, and smells and everything been....off...and been taking naps for 3+ hours a day because I'm so utterly exhausted even after sleeping for 10+hrs. And last night I went to go make chicken-almost threw up once the smell hit my nose.

Idk im probable just going crazy.. but..Opinions?
