NUH gynae check up

Hello, im currently 33 weeks and my next appt for normal check up( hear heartbeat etc) is suppose to be next week. However, they changed to 13 June which means by then I am already 37 weeks. Isit normal? by right I think I am suppose to be getting check up every 2 weeks….? Isit anything to be concerned about/need to call clinic to ask the reason for the change? #firstmom
