Ay, congrats mama! But ito talaga ay something you need to discuss with your OB right away, even if you're excited, only your doctor can say kung ano ang best para sa iyo at baby at this stage, kaya please don't wait and reach out to them today. Two centimeters this far along is something they need to monitor closely, and walking or any activity really depends on what your doctor advises for your situation, walang one-size-fits-all dito! Wishing you and baby all the best, mama. Keep safe!
