"Antenatal early pregnancy emergency clinic"

I am 19 weeks pregnant. I visited the clinic for pelvic pain, essentialy in the groin area, with difficulty walking, and turning during sleep. The clinic is open in the morning, on a first come first seen bases and level of emergency. I've spent nearly 2 hours at the hospital. When I arrived I've been 7 on the cue. There were enough chairs. The waiting time was acceptable. After a quick chat I have been sent for a checkup ultrasound by the midwife. I waited again. I've seen the midwife again afterward. Everything was fine with the baby, but it didn't explain my pain. The midwife was kind, understanding for my concerns, and very open at my suggestion. I showed her a reseach about Pelvic Girdle Pain, and she happily refered me to the physiotherapy unit.
