Ay, normal lang yan usually sa early pregnancy, sis! Ang ligaments natin ay nagsisimula nang mag-stretch at mag-adjust kaya may mild aches and pains, lalo na sa sides ng buo, a few of us actually experienced the same thing around weeks 4-6, tapos nawala lang after a few weeks. But since may kasama pang pang-numbness, I'd really suggest checking with your OB just to be sure, kasi sometimes it can be something that needs monitoring, especially in early pregnancy.
