Hi mama! Some cramping is normal sa early pregnancy, but dahil maigi-guide ka ng OB mo based sa your specific situation, I'd really suggest checking in with your doctor about this para ma-rule out kung iba lang or normal ligament stretching lang talaga. A few of us tried na mag-worry lang at it turned out fine, pero better safe than sorry, lalo na ngayon pa lang kayo sa 6 weeks pa, your doctor can do an ultrasound to check everything is okay. Praying all is well with your pregnancy, mamsh!
