I’ve been learning about herbal contraceptives and abortions for a bit now, and was curious if anyone has had a successful abortion?

What herbs did you use?
Tea or tincture?
Dosages?
If it was successful, how did your body feel during and afterwards?
If it wasn’t successful, did you continue the pregnancy or have a medical abortion?

One book I am reading states that there is a study that proves a 47% success rate. But I want to know from first hand accounts.
