Sent home twice maybe next time it will happen

Went to the hospital last friday thinking i might be in labor..nope ..got sent home. Today.. I was having non stopped contractions every five mins..they checked my cervix only 3cm and 80 percent effaced..which hasn't changed since my last cervix check which was on monday. Doctor said contractions are not strong enough to dilate me but soon she will come...i got sent home again...lame..I'm 37 wks.. Baby girl already weighs 6.4 pounds..this is my second baby.

My first baby came at 34wks due to me getting really sick.I was admitted at the hospital at 32wks because i was in pre term labor..They stopped my labor and i stayed in the hospital till i had him.Between 32wks and 34wks i had gotten really sick...i got preeclampsia..hypertension...toxemia.. my kidneys and liver start failing...so they had to induce me...they broke my water...i was in labor 36 hours or more and they started prepping me for a c section but at the last min i dilated. I dont remember anything from that birth..i had an epidural and 14 other different medications that i was on..My son weighed 4 pounds 5 ounces. POINT IS YAY I MADE IT THIS FAR...baby girl is healthy and im healthy.. I am just having a hard time figuring out these darn contractions and what to expect... I never made it this far ..it is scary not knowing what to expect..im feeling everything and not used to being this big lol....
