Official answer

by Drugs.com
Yes, Plan B (levonorgestrel) may lead to a delayed period or induce bleeding outside the typical menstrual cycle, as it contains a synthetic hormone. In order to prevent pregnancy, Plan B, similar to other contraceptive pills, needs to modify your hormonal levels, which can result in these menstrual alterations. It's worth noting that Plan B is linked to a higher likelihood of menstrual changes compared to regular birth control pills, due to its increased dosage.
