It's not unusual for someone who had an abortion not to menstruate right after. Their bodies may take up to 2 months to reestablish the natural cycle. Few points that need attention are that there can be severe vaginal fluid, fever, or pain (jaundice). When experiencing these infections could develop. Infections will need treatment with antibiotics. Your period may eventually continue not to come, but if you're worried about it, go to your doctor. If you notice anything unusual, seeking some medical advice by a gynecologist would be the best solution.
