Sis, please go to your OB or emergency room today, bleeding with belly pain in pregnancy, especially as a first-time mom, kailangan i-check agad ng doctor, hindi dapat i-guess. Once you're cleared by your doctor, sila na ang magsasabi kung ano ang safe na ilagay sa katawan mo right now, including any oils o supplements, better to ask them directly kaysa mag-try on your own. Sending you love, mama. Go get checked.
