35w na ko based on my LMP pero based sa utz ko 26w5d lagi na tumitigas tyan ko. As in mayat maya

Mama, this timing mismatch is something your OB really needs to sort out properly, please bring this up sa next check-up, or call them now if you're worried. The difference between LMP at ultrasound dates can happen, pero kailangan nila i-clarify kung alin ang accurate para ma-monitor mo nang tama, lalo na with the regular tightening you're feeling. That said, Braxton Hicks (practice contractions) around mid-pregnancy onwards ay normal, pero palaging better safe than sorry pag may doubt.
