How long is it going to take for the side effects to subside?? (micronelle)

I got on the pill maybe half a week ago and I genuinely feel like a breathing corpse. I was told there would be side effects but I didn’t realise they’d be this bad- i get these stabbing abdominal pains, I feel nauseous constantly and have throbbing headaches. I can’t sleep properly and so I’m constantly running on 2 hours sleep. Is this just all part of the gig??? It’s affecting my school and work and if anyone’s had any similar experiences please let me know how long it took to calm down 🙏
