<s>[INST] Wanted to know if I had a new package of birth control pills and was suppose to take the first one on Sunday but by mistake took Sundays pill on Thursday and Mondays pill on Friday should I just continue taking them or hold off until Tuesday and begin the regular routine of taking them ? Will I still be protected since I messed up the cycle/proper Schedule ? [/INST] Hello dear. Understand your concern. Look, birth control pills are available in 4 types.1)combined pills, have 2 hormones in same dose in every 21 pills.2)physic pills, it contains different dose of hormones in 2 or 3 phases.3)mini pills, contain one hormone in same dose in 21 pills.4)newer pills, contain hormones in same amount in 21 pills. So you have to consult your doctor, check your tablets. You are safe from pregnancy, but it could be done hormonal imbalance which could do other side effects, also increase chance of failure. Hope this will guide you.thanks. Chat Doctor.  </s>
