Has anyone ever gone into preterm labor? Is it painful and totally obvious? I'm 25 weeks and I have vaginal pressure, menstrual like cramps, dull lower back pain, and my contractions are punching closer together, plus baby is lower than normal this week way in my pelvis..but it's not painful, just uncomfortable....I'd run off to the hospital but I'm a single parent and my 6 year old is completely asleep and my 11 year old is almost asleep and the hospital is 30 min away...
