Went to the hospital today

Jessica • I am 28, married, we have a 6 yr old boy and currently pregnant with our daughter :)
Went to the hospital today because I was having tons of Braxton hicks contractions that were making it so hard to breath and they wouldn't stop.  I haven't dialated anymore but I was having some contractions just not close enough together or painful so they sent me home ? I am still having the little contractions so hopefully they will start coming stronger and closer together soon!!
