ALERGIC REACTION TO BIRTH CONTROL

So I’m taking mirvala 28, and I just had a serious alergic reaction. My Face swells up and I get hives all over my body. I want to stop taking the medication mid pack but I’m afraid of the consequences. I heard you have to keep taking the pill 7 days after unprotected intamacy, so I can’t stop taking it right away. However I’m thinking of switching to a new pack tomorrow & then stop taking birth control all together after getting my period.

Has anyone every had a similar experience? Would love to hear what you guys have went through
