Sayang, this needs a doctor's check-out ASAP especially if the cramping is strong or keeps happening, don't delay on this one, okay? Persistent cough during pregnancy boleh put pressure on your belly, but cramps mixed with cough kena make sure everything's fine with baby. Call your gynae or go to the nearest clinic/hospital today to be safe. A few of my mum friends had similar worries and doctor visits put their minds at ease, so jangan worry, just go check lah. Sending you strength!
