Hi, I’m On Mercilon Contraception Tablets. I Took 2 Packs

Hi, I’m on mercilon contraception tablets. I took 2 packs back to back but with this 2nd back I have been taking in the last week I missed 2 pills. I took the pills 2 in 1 day when I remembered and then took them correctly then I forgot to take the pill 2 days again. So today I will take the 2 missed pills but do I have a 7 day break or start a new pill pack again. That will be 3 back to back packs though. Please help, I do not want to get pregnant.
