I am experience cramping sensation. I am only at 28 weeks now. Is it common? Am i at risk for preterm labour?

If your cramping doesn't come with any pain, it might be Braxton Hicks. Braxton-Hicks are 'false labor', it is a way to practice contractions that get your body ready for your baby’s arrival. Signs you’re having Braxton-Hicks contractions include: -contractions that come and go -contractions that don’t get stronger or closer together -contractions that go away when you change position or empty your bladder If there is a pain accompanied with the cramping, it might be an indication of uterine contraction and cervix dilation which leads to pre-term labor. Please visit your gynae as soon as possible and gynae will check on your cervix length to see if the cervix is still intacted.
