Oo, alam ko yan! Round ligament pain talaga yan, super common sa pregnancy lalo na paglumaki na ang belly, parang stabbing or pulling sensation sa side, diba? A few of us moms experienced it, and honestly nakakatakot ang una pero normal lang siya as your ligaments stretch to accommodate baby. Para sure though, I'd still mention it to your OB just to be on the safe side, especially if severe or may other symptoms na kasama, pero most likely walang alalahanin ka, just one of those pregnancy joys haha!
