Ay sis, that feeling ng pagmumulikat sa butas ng pwet while baby is moving around, honestly, I'd have that checked with your OB ASAP kaya lang, especially since you're on bed rest na for preterm labor risk; hindi ko seseryoso yan kahit normal ang kicks pa naman usually. One of my mum friends had something similar at first she thought normal lang, pero it turned out related sa nerve pressure from the baby's position, kaya mas safe talaga magpa-assess. Get in touch with your doctor today if pwede, okay?
