Uy, I totally get the worry kasi parang weird yung feeling, but honestly at 2 months yan parang normal pa, maraming reasons bakit may ganyang sensations, from ligament stretching to kung paano ka natutulog, pero sobrang better to check with your OB agad lang para makakuha ng peace of mind, especially kung intermittent lang talaga at feeling mo nangangalay lang. A few of us moms felt something similar and it turned out to be nothing serious, pero walang sense magalala when your doctor can easily check and confirm everything's okay with baby! Let me know what your doc says, okay?
