Method of abortion is dependant on dates.
Dates are often wrong because of circumstances surrounding the conception (I could cover every scenario but this is not meant as an insult but as a representation of anecdotal evidence working in a termination clinic).
Many women know exactly how pregnant they are. Knowing which these women are, is not something Dr's are capable of.
Performing the wrong technique could be hazardous to the woman and certainly open Dr up to litigation if it went wrong
I saw many a woman who had a scan performed in a newly set up termination private practice where the scan/protocol had been performed inadequately and the consequences varied but were not good for the woman. Missed ectopics. Miscarriages (incomplete abortion) given a D&C anyway (op risk and distressing to the woman who had already miscarried but this knowledge was only obtained once she had instruments inside her), unusual shape to uterus and varied risks of surgical procedure. You can have a positive preg test even when you have miscarried. You'd then have an unecessary procedure.
A scan would have given a safer procedure. I would never consider a TOP myself without one.
The womb is not measurably palpable in v early preg.
Abdominal scans are good in a slim full bladdered woman with no bowel gas.
Vaginal scans are however the technical gold standard for visualisation. It should never be performed without valid consent. Never.
I think the assumption that staff use vaginal exams as a punishment rather than as a medical examination for the patient's benefit is insulting to clinics who offer a professional, caring and sensitive service to women requesting abortion - they use it to provide gold standard care. If you decline then that should be accepted as your wish and recorded with you taking responsibility for any consequence. No problem to either party involved that way
We never ever showed the screen and we answered questions as asked and never volunteered information.
