Where to go for ultrasound?

Hi all, I had light pink bleeding the last few days (I’m around week 11 now), coupled with abdominal cramps that feel like it’s period cramps. Morning sickness has lessened quite a bit too, not sure if it means the hormone level is falling. The bleeding is not bright red and it comes and goes, but I’m very worried for my baby. Is there anywhere I can go for an ultrasound to check whether it’s ok? The worry keeps me up at night. And I’m super grumpy and angry this week, very obvious mood changes - is it normal during week 11? PS: I’m seeing NUH for my gynae care, but I don’t think I can just call in the main hotline and ask for an ultrasound to check on the fetus ? #advicepls #pleasehelp
