Spotting like this after an emergency contraceptive pill is common. It's the hormone shift affecting your lining, not a sign of a problem. Your next period can come on time, early, or delayed by a week or two, it varies between women.
Next Steps
Eat iron-rich foods like leafy greens, dates and jaggery, along with protein, to help with the weakness, and rest when you can. See a gynaecologist if the delay runs past three weeks.
Health Tips
Go in sooner if the bleeding becomes heavy like a period or lasts more than a week.
