An underground doctor may turn out to be a layman, and in general, not everyone understands what he is doing. The clandestine doctor is unlikely to have modern safe equipment. In a clandestine operation, it is difficult to ensure the proper level of sterility of instruments and, in general, the overall sanitary situation. Well, everything pops up from here.
Abortion is, in principle, dangerous for a woman's health. For example:
Rhesus parent conflict (if any). The outcome of an abortion in this case: difficulties with the subsequent pregnancy, its course and the birth itself in the aftermath are in question. Exit: Immediately within 48-72 hours. to inject a woman with immunoglobulin. Now attention! Will you get an injection like this? No. They won't even do an analysis for you, and they won't even ask you about the group and Rh of your parents' blood.
Injuries. Well, here is a separate topic altogether. If this is curettage (mechanical abortion), which is the most likely scenario in the underground, then be prepared for complications. The procedure assumes sterility! Time. Competent specialist with appropriate education! Two. Otherwise: endometritis (google) for example and so on.
Follow-up by a doctor. Oh, what can I tell you? Where would such a woman go? Just back! Imagine the eyes of a doctor in a polyclinic. Have you presented? So she will present and will not go to an experienced doctor. In general, in principle, she should be concerned about the issue of competence "underground". She thinks to herself "a good doctor, blah blah", but why does a "good doctor" earn money underground? After all, now good obstetricians are worth their weight in gold. Everywhere they are dear! And they have the money from it, gay! So what went wrong with your "good doctor"? Maybe he will not work out with you?
IMHO, in general, as giving birth. If childbearing is not now, but in principle, the expectant mother is interested, then contact ONLY to honey. institutions.
They can't prove otherwise, can they?
