They have to ask, there are various ways they do it, in my local health authority they have packs of red sticky dots in the female toilets so when the lady goes to produce her urine sample they can stick a dot on the tube if they want someone to approach them discretely about abuse.
While in the normal course of things I would agree that male domestic abuse is something that is swept under the rug, in these circumstances while pregnant and soon after childbirth, ladies are more vulnerable than normal so it is right there is a little more focus on their wellbeing, it isn’t an attack on the dad.
