Uy mama, yan ang pelvic girdle pain or symphysis pubis dysfunction, super common sa huling weeks ng pregnancy, pero grabe talaga ang sakit niya! A few of my mum friends had the same thing near the end, lalo na kapag maraming movement or standing ka ng matagal, kaya karamihan sa amin nag-adjust lang ng positions at gumamit ng pelvic support belt na tumutulong talaga. But mama, since 38+ weeks ka na, definitely mention this to your OB next check-up or kahit i-call mo sila kasi they might want to see kung may other concerns pa, especially if the pain is getting worse, importante na alam nila severity para ma-guide ka ng maayos through labor pa lang. Praying for you, mamsh, liliit na lang ang ipon!
