But catsmother there are a lot of other potential negatives to pregnancy and birth that might have been unpleasant for her to even contemplate, some of which even the best victorian medical care couldn't have prevented:
Very real likelihood of death in childbirth from an obstructed labour or haemorrage, transverse baby, eclampsia, cord prolapse, placenta previa, placenta accreta, joint pain, incontinence, risk of dying from puerperal fever after the birth (lessened as her doctor, Dr Snow was aware of the need for hygiene), depression, mastitis, breast abcesses, high blood pressure, low blood pressure, anaemia, fistulas, damage from doctors using instruments, tearing and infection, prolapse, miscarriage, stillbirth, death of baby in first week or months, a long labour with no anaesthetic - I believe she tried chloroform with her seventh and eighth labours (or eighth and ninth) but the general expectation was that women were supposed to suffer in labour -its Eve's punishment for tempting Adam. There was also a general movement that said that labour pain was different to surgical pain and didn't need anaesthesia- see Dr Meigs etc. See here for doctors reaction to her using anaesthesia - subtext under the fear of her death is that she had perfectly normal labours so why would she want pain relief?
In 1817 Princess Charlotte died after 50 hours in labour, the baby was stillborn. It was her death that set in motion Victoria taking her place on the throne (and the childlessness of her uncles- in one case due to several infant deaths) so recent (and past) history would have demonstrated the importance of having lots of children and the potential risk.
