Uy mama, sharp pains kahit nawawala at bumabalik deserve a quick check with your OB, better safe than sorry, lalo na kahit 18 weeks pa lang, especially kapag FTM ka at nag-overthink (which is totally normal, ha!). A few of us mums had similar experiences and some turned out to be ligament pain, pero iba-iba talaga, kaya doctor lang talaga ang makakatulong ma-rule out anything at magbigay ng peace of mind. Just give your OB a call or mag-book ng appointment agad, okay? Take care!
