Hey mama, yan talaga ang Braxton-Hicks contractions, super common na yan around 35 weeks, parang practice lang ng katawan mo for actual labor! But since you're almost full-term na, it's still best to mention it sa OB mo next visit or call agad kung sobrang sakit na or may discharge, para sure lang na lahat okay. A few of us moms dito experienced the same thing at hindi kami worried after doc confirmed, so trust your instinct pero don't hesitate to reach out sa doctor lagi.
