Oo, super normal yan! Those are Braxton Hicks contractions, at marami sa amin na third trimester na rin nararanasan yan, ang tiyan mo lang gumagawa ng practice contractions bago pa mag-deliver. Pero kung sobrang sakit na, sobrang frequent, or may spotting / discharge na unusual, better check with your OB na lang para peace of mind mo kasi first time mo pa lang talaga. Iba-iba naman kasi ang pregnancy journey ng bawat isa, so mas safe na i-confirm sa doctor mo. Breathe lang, mama, you're doing great!
