Sis, appendicitis while pregnant is really something you need to have checked by your doctor or go to the ER right away, hindi ito dapat hintayin. I know it's scary, lalo na first baby mo at 10 weeks pa lang, pero mas safe talaga na makita ka ng doctor agad para ma-rule out or ma-treat properly. A few of my mum friends had emergency situations during pregnancy, at ang best thing talaga they did was go in immediately instead of waiting, peace of mind lang na alam mo na baby mo is okay and you're in good hands. Please don't wait on this one, mama. Sending you love.
