Labor at 30 weeks

So my water broke and this is my 3rd pregnancy. My other 2 were actually pretty normal but this one was different from the start, I knew I wouldn't make it to 37 or even 38 weeks but I thought I would at least make it to 35 or 36...I feel like I did something wrong even though I know I didn't, but I just cant help feeling like I did something to cause this...they're trying to keep her in there safely as long as possible they said hopefully 34 weeks at least. My husband cant be here because he's home with the other 2 kids, so I'm by myself feeling like I'm dealing with this alone and I hate it. I just dont know why this is happening. Please if anyone went through something similar let me know how your baby turned out, I really need reassurance. Especially what to expect with the nicu stay.
