Hello pharmacist,
I finished the 21-pack of birth control pills, waited 7 days for my period, but I haven't had one yet. So the pharmacist told me how to take the 21-pill birth control pill? Should I continue taking the second pack to prevent pregnancy or wait for my period to take it? Thank you pharmacist.

Hello,
With the question "How to take the 21-pill contraceptive? ", the pharmacist would like to answer as follows:
Daily oral contraceptives usually contain estrogen and progesterone (these two female sex hormones), have the effect of preventing ovulation, thickening the cervical mucous membrane, preventing ovulation. Prevents sperm from swimming towards the uterus to fertilize, changing the uterine wall not suitable for egg implantation, thus preventing pregnancy. Currently, on the market, there are many daily contraceptive products, divided into two types: blisters of 21 pills and blisters of 28 pills.
For oral contraceptive pills of 21 pills, the way to take them is as follows: 1 pill/day, from the 1st day of the menstrual cycle, continuously for 21 days, take a break for 7 days and take the first pill of the next pack right after 7 days off. Thus, the first pill of the pack is always taken on a fixed day of the week, for example, the first pill of the first pack is taken on Monday, the first pill of the second pack is also taken on Monday, exactly 4 the week.
You start taking the 2nd pack no matter what day your period occurs. At this point, you do not need to care about which day your menstrual cycle will appear.
