Aww congrats on 12 weeks, mama! Pero seryoso, kahit na parang mabilis lang mawala ang sakit, please check in with your OB agad-agad, ha? Better safe than sorry lalo na sa first trimester, kaya go na sa clinic or call them to describe what you're feeling. Alam mo naman, pag buntis tayo, any new sensation dapat i-confirm with the doctor para walang worry ka. Sending you good vibes!
