Aww, I'm sorry you're not feeling well! Since you're asking about tummy ache relief, best talaga na i-check mo muna with your doctor, lalo na kung matagal na or if you're pregnant/breastfeeding, gusto lang natin i-make sure it's nothing serious, you know? A few of my mum friends swear by warm compresses on the belly (parang yung hot water bottle or lamig lang ng malambot na tela) para sa minor cramps, but honestly the safest route is to have a medical professional look at it especially if you're nursing or expecting, since maraming OTC options na hindi recommended sa phases na yan.
