It’s important to note that your period might be different after taking Levonorgestrel. Most women will get their period at the normal time, as expected, but some may get it later or earlier. If your period is more than five days late, irregular, or unusually heavy or light, you should talk to your doctor as soon as possible.
Other possible side effects are tender breasts, diarrhoea or feeling dizzy. There have also been reports of very rare effects, such as a rash, itchiness, swelling of the face, pelvic pain and painful periods. Again, if you’re concerned about side effects or think you’re having a reaction, let your doctor know as soon as you can.
