Thanks for your query.
Ideally 48 hours after the first tablet, 2 tablets should be taken and 2 more later.
Not 1 as you have described.
It takes upto 15 days for bleeding sometimes.
If you have taken pills without consulting a doctor , do so IMMEDIATELY.
These pills should be taken only after consultation with a gynecologist.
should be confirmed and dated by the doctor, and then only pills should be taken in dosage prescribed.
follow up visit to confirm completion is also a must.
WIthout such steps, risks such as severe bleeding, infection, incomplete abortion
All the best.
