Since you did not effectively miss any dose ( as you claim to have made up immediately), your cycle should be protected well enough. Had you missed a pill and made up after a day, two pills should be taken in the next dose or additional protection sought. In the current scenario, you can exclude/confirm pregnancy
through estimation of the serum beta-hCG
titres along with a clinical evaluation before you start on your next pack of pills. if negative, you can go for the next pack even if you do not see a period. Hope this helps.
