Ay, best to check with your OB muna before mag-adjust ng braces, kahit routine adjustment lang, gusto mo sure na okay with your pregnancy first, especially since you're still in the early weeks. A few of my mum friends na nag-braces during pregnancy kinonsulta nila both their dentist and doctor para sigurado, kasi hormones and all that can affect your gums at teeth din. Your dentist can probably do it, pero better safe than sorry talaga when you're pregnant, no?
