I've been having contraction since about 9 it's now 1:40 am the contractions have gotten a little more intense over time. So I called the hospital they said I could come in and get checked but said usually the contractions I will be in enough pain that I'll need to breathe through them... They are about 5 min apart around 30-45 seconds each they stopped for about 15 minutes then came back again now about every 4-5 minutes....should I go in?
