@rhythm,
I agree with buttermilk the information you provide is scarse. Mifepristone, the formula of Mifeprex is a widely used drug for abortion, which is a legal use in many countries. In mine actually is, so i speak bluntly about it.
Thats why ne/she insist in this point he/she is guessing you use it. So it will be a completely normal side effect of that drug and theres nothing you can do to stop it but wait.
Other possibility is that you had used an emergency pill. i had knownmany patients that confound them with abortion pills. In which case the effect will vary greately depending on the days you had since the conception of the product. More information is needed.
Although there are signs of abnormality on the bleed caused after an abortion pill like heavy bleeding for more than 3 days, strange color of the blood, bad smell of the blood, intense and persistent pain, important belly swelling, and others.
The best bet is to look for a doctor of your trust. I highly recommend to look for doctors who take their time to explain everything, that takes his time to listen to your doubts, and that makes a tratment plan (of course explanation included), and stick to them forever.
Ask someone you now with a child with asthma. Since their disease is really troublesome, those parents trend to know a lot of doctors (general practitioners and emergencyspecialists).
