Wa'alaikum assalam sayang! Eh this sounds urgent, please go to the hospital or call your doctor/midwife right away, okay? Contractions every 10 minutes even without the cervix opening fully is something they really need to check properly, especially for your first baby. A few of us mums have gone in thinking it's false alarm, tapi the doctor said better safe than sorry, they can monitor baby and you properly. Don't wait, go now ya! Wishing you all the best, mama!
