Although your period may not come for several weeks after your abortion, you can get pregnant again right away after an abortion, even if you are still having some light bleeding. This is because ovulation can happen at any time after an abortion. If you want to avoid becoming pregnant, you should start using contraceptives immediately after the abortion.
You can use condoms and other contraceptive methods right away after an abortion. An IUD can be put in place as soon as the abortion is deemed successful on ultrasound, usually 4 to 14 days after you have taken Misoprostol, even if there is still light bleeding. You can also wait to insert an IUD until your next regular period, but you will need to use another contraceptive method in the meantime if you do not want to risk becoming pregnant.
You can start most hormonal contraceptive methods (such as the oral contraceptive pills, vaginal ring, injection, implant) immediately after an abortion with pills. If you start oral contraceptive pills later than 3 days after using Misoprostol, it is recommended that you use condoms during the first 9 days, until the pills reach their full level of protection.
