Uy, yan talaga ang common sa 34 weeks, lalo na if you're carrying high or if you've been standing a lot! A few of us moms experienced the same thing, sometimes it's just the weight ng baby + hormones loosening up your ligaments, pero since it comes and goes, mas okay na yan kaysa constant pain. That said, better mention it sa OB mo next visit para sure lang, especially if it gets worse or may other symptoms like spotting or contractions na regular na.
