Sayang, cramping in early pregnancy boleh normal, tapi since you're worried and it's quite bad, please call your doctor or go to the clinic/hospital today , better to check and put your mind at ease, kan? Tak ada bleeding is a good sign, but cramping yang terasa strong macam tu kena confirm dengan doctor je, especially at 10 weeks. A few of my mum friends went through similar and turned out OK, but some needed a quick scan just to make sure everything's fine. Don't wait, go get checked out, yeah? Jangan risau, doctors see this all the time.
