Ay, that numbness feeling sa belly ay common sa early pregnancy talaga, lalo na pag nakatuon ka sa pagbabago ng katawan mo, parang nag-overthink lang tayo sometimes! But since it comes and goes, I'd still suggest mentioning it sa OB mo sa next checkup para sure lang, especially since you're still very early pa, walang masama sa peace of mind, diba? A few of us had similar sensations sa first trimester and it turned out fine, pero better safe than sorry talaga when it comes sa pregnancy, so definitely bring it up with your doctor para ma-check properly.
