Do not concern much.
Remember this facts first:
A
medical abortion usually requires at least two visits to your doctor over several weeks.
For the first visit, one medicine (mifepristone) is taken during the visit and a second medicine (misoportol) is given to be taken at home.
The second visit is a follow-up appointment, usually scheduled about 2 weeks after the first visit, to make sure the
pregnancy has ended and no complications are present.
If a medical abortion is not successful, a surgical abortion is then done to complete the process because
misoprostol can cause fetal abnormalities.
Now comes to your question, you have taken both the drugs as prescribed by your doctor, and you have bleeding heavily.
So there is no need to take next dose of misoprostol.
Just consult your doctor after 1-2 weeks and go through the examination to confirm that your abortion has been complete.
All the best. take care.
