What if you have a positive pregnancy test after abortion pills?

If the pregnancy test is still positive after 3 weeks, it is important to get a medical evaluation right away as you may have an ectopic pregnancy, which can be dangerous.

Recovery period after abortion pills

Your body might need several days or weeks (until your next menstrual period) to expel the tissue and blood completely. The ultrasound will show what is still in the uterus. Some doctors will recommend a vacuum aspiration, but if you have no pain or fever or signs of infection, it is better to wait and let your body empty naturally. A vacuum aspiration or a D & C is an invasive procedure that involves risks and can be painful.
