Getting ready for baby.... Need info please!

Im 19 and 30 weeks pregnant... I keep going into labor and they keep giving me shots to stop it... But Im worried Im going to have her early... I was wondering if anyone had any information to help me out about what to expect on having a premature baby... Or just having a baby at all... I feel like theres so much I dont know. And so much for me to learn...
~Thanks

relax and breathe. take it ease. stress can cause you to go into early labor. i was the same way. everybody thought i was going to have my baby super early, but she came within time. dont freak out about a premature baby at 30 weeks. they baby will most likely survive. my sister had her baby wen she barely turned 7 months. and hes doing just fine. just take it easy and dont over-exhaust yourself. i just turned 20 on the 1st so i know what your feeling. everything would come to you as the days get closer. you have the mother instinct as soon as your baby cries... its a beautiful thinmg
