The answer to the question of whether you can take birth control pills for 20 days after an abortion is no. There is a normal cycle and time for taking birth control pills, usually after the abortion surgery, you can start taking birth control pills at that time, and according to the instructions, there can be no omission. After 20 days after the abortion, the ovaries may already have egg development, and may resume ovulation, when there will be menstruation, this time period is not the time to take birth control pills. In addition to taking the pill at the time of the abortion, another option is to take the pill at the time of menstruation to make sure that you are not pregnant. Therefore, 20 days after the abortion, with no possibility of pregnancy excepted, and without menstruation, this is not the right time to take the pill.
