Aw first time mom worries, gets it! Yung nausea at breast tenderness ay super normal sa early pregnancy, maraming pregnant friends ko na ganyan around 7 weeks, pero yung paninigas ng tyan at sakit sa ari need mo talaga i-check with your OB, hindi scary, basta peace of mind lang para sure na lahat okay sa baby mo. Bili ka na rin ng prenatal vitamins if wala ka pa, and try to eat small frequent meals para sa nausea, works wonders talaga!
