Earliest O&G appointment - 13 weeks

Hi, just got a call from NUH today that earliest O&G appointment they have at Clinic G is 13 July for my first visit. I’m currently about 7 weeks pregnant and by then would be roughly 13 weeks. Is that ok or too late for a first appointment? I’ve gone to GP and polyclinic to confirm my pregnancy and it’s a positive. Just thought a scan should be done in the first trimester 🤔 Anyone else went for their first O&G visit after 12 weeks? #firstbaby #advicepls
