Hay, alam ko that feeling, mama! I think it's better to mention this sa OB mo sa next check-up kasi may lots of reasons pwedeng maging cause, sometimes it's just the weight ng baby, increased blood flow, or ligament stretching (super common yan), pero kailangan talaga niya ma-check if may UTI or other stuff para you'll know for sure, especially para sa peace of mind mo. One of my mum friends had something similar at nung tinanong niya ang doctor, nalampasan lang niya before kasi nag-assume siya, so better safe na lang talaga!
