Ay mama, leg cramps during pregnancy are super common talaga, lalo na around your weeks kasi lumalaki na ang baby and mas heavy ang katawan mo, pero kung parang ganyan ang intensity and hindi ka talaga makakilos for 3 days, better check with your OB na lang to be safe, hindi mo alam kung may something else going on like blood clots or nerve stuff, you know? A few of my mum friends had similar cramping pero mild lang, so this sounds a bit more than the usual, babe. Drink lots of water, stretch gently, and get that appointment scheduled agad para peace of mind mo!
