Oo, around 7 months na yan (26 weeks is approximately 6+ months, heading towards 7), kaya normal lang na lumalaki ang tyan mo! Para sa pain sa singit or around the belly area when you hold back your pee, sis, please check with your OB about this, lalo na since you're pregnant. It could be normal stretching, pero mas safe na marinig directly from your doctor kung ano talaga ang nangyayari, especially sa ganitong sensitive time. A few of us moms had similar concerns and our doctors were able to explain exactly what's safe and what needs attention. In the meantime, try to pee when you feel the urge na, don't hold it too long, okay? Sending you love!
