First scan at 12 weeks, is it normal?

when i first went to polyclinic, i was at week 6. they wanted to schedule appt the with KK following week, but i thought it's too early (on first visit they normally do scan but if it's too early, you still need to do another scan post week 8 for dating scan for more accurate EDD). so i asked to push back another week so i'll only go KK at week 8. on that first visit, they already laid out schedule for FTS at week 12 and 20 week scan. i think NUH has a longer waiting time. you can try call if can reschedule earlier and let them know how far along you are. especially if you're keen to do FTS (first trimester screening) that needs to be done before week 13. i imagine they'll need time to secure appt for that (also need to do blood tests prior). i'd be anxious too if i'm you.. good luck mama!
