Check up

Do u think it's alright to do my 1st check up at 9 weeks? Then skip the next few check ups till 16 or 20 weeks? This my 2nd pregnancy. I'm wondering if any mummies here has PCOS & preg or ever preg? My 1st check up next Tues however I am praying that all is gd cos my gynae said PCOS pregnancy is a risk.
