Ay alam ko yan, nakakapakaba talaga! Light pinching or cramping sa early pregnancy is usually normal kaya don't worry too much, pero since you're actively feeling uncomfortable, best i-check mo na with your OB para peace of mind, maraming reasons pa yan pwedeng maging (ligament stretching, baby movements pa lang, or something else) so better safe than sorry! A few of my mum friends also felt similar cramping around that time pero nag-settle lang, pero importante talaga na confirmed ng doctor mo specifically. Keep hydrated, rest well, at mag-message sa OB clinic ninyo if it gets worse or you have bleeding, okay?
