your gynec will ask for an anomaly scan now if it hasn't been done.
No need to scan every month if all is going well.
there is no known side effects of ultrasound rays to the foetus.

An anamoly scan be be recommended before you reach 20 weeks. A total of minimum three ultrasounds are required during pregnancy.
