So discouraged 😔

I'm 36 weeks and Monday night I was having some terrible contractions. So my husband and I went to the hospital and got checked in and what not. Well they checked me and I was dilated to a 1 and my water was leaking. They went ahead and put an IV in and them ordered a ultrasound to check my fluid and find out her weight approximately. She's about 7lbs and 3oz and my fluid was fine. About 5 hours later, I was checked again and was at a 2 and 75% effaced. So we were all excited cuz we figured we were gonna leave with our little girl. Well the next day, my doctor came into check me and I was still the same. So he decided to send me home with contractions and my water leaking. I just feel so down because now I have contractions and back pain all the time and they told me unless your contractions are strong and. 5 mins apart or your water totally breaks, just take it easy. Very irritated and upset 😔 so glad I have my check up tomorrow to see what my doctors plans are now. I just don't wanna have a HUGE baby...
