My son was born at 35 weeks 7 weeks ago, my waters just went spontaneously too. Waters went at 8am and proper contractions (as opposed to uncomfortable tightening) started at 2am and ds was born at 11am the next day (29 hours after water broke).
Try not to worry too much, I know easier said than done. My ds spent 8 days in neonatal and then came home and he has been absolutely fine since. Although he did need help breathing for the first 6 days (more at first and decreasing gradually) he was jaundiced and spent two sets of 48hrs under the lights. In my case the reason my waters broke was because of an undiagnosed infection (strep b) which was only found out after birth, luckily my ds was already on a precautionary course of antibiotics he did develop a chest infection and stayed on antibiotics for 5 days. He had a few other minor issues but honestly you would be amazed at how fast these can and often resolve themselves in newborn babies, every day seem like a totaly new beginning.
A couple of things I would like to mention (which may or may not be relevant to you depending on how your baby is at birth)
- They may do a routine brain scan on your baby on day 1-2, if they find bleeding on the brain try not to panic, apparently varying degree of bleeding on the brain is perfectly normal and harmless in premature babies (even as late as 35 weeks). My ds had bleeding on the brain and I absolutely panicked because no one told me until 3 days later (when they repeated the scan) that this was actually perfectly normal and nothing to worry about in most cases and that they were only monitoring. We had to go back to hospital at 4 weeks to have the scan repeated again to make sure it was continuing to resolved itself and in our case it was gone and normal.
- If your dd spends any amount of time in neonatal try if you can to be there for the doctors rounds because you get the whole history from birth everyday day and you get to hear everything they are planning, have done and all the issues that have already resolved themselves. Ask as many questions as you like and make your presence known to the doctors so that they in turn communicate with you.
I hope I'm not scaring you, it really isn't my intention, I just wanted to share my experience because when my ds was born I really wasn't prepared for how it would be. He is my second and when dd was born she was with me all the time and it was very hard to watch him go to the neonatal ward before I was even stitched all up. It's not fun and it's hard but in many cases it a very brief period and soon baby will be all well and strong and back home before you know it. Also neonate units can be very intimating, with all the machines, tubes and beeping, it pays to remember that although you dd may look very unwell (if she needs a tube for breathing for example) she probably isn't as poorly as she looks and she probably is much stronger too.
On the other hand she may be absolutely fine and require no help or very little help. Sorry I'm rambling, I'm just very aware that this is all very imminent for you and you are probably really scared and I don't want to make it worse I just sometimes it helps to be prepared.
Hope you are feeling ok and that it all goes really well for you and your dd, I wish you both all the best.
