Hey mama, congrats sa 8 months na! Normal lang yan, ang mga Braxton Hicks contractions (yung tightening) lalo na pag puno ang tyan or kailangan mo na mag-CR, ganyan talaga, pero always better to mention it sa OB mo next checkup para peace of mind mo lang, especially since first time mo pa; and yup, ang weird sensation na parang mag-ihi or mag-poop pero hindi talaga nangyayari ay super common din sa late pregnancy kasi ang baby at lahat is pressing down there! Isa sa mga mum friends ko grabe ang experience niya dyan, parang she couldn't tell the difference between labor signs and false alarms, kaya just keep track lang if the tightening gets regular or painful, pero otherwise, you're doing great!
