When I had DD 6 years ago, I remember being in labour for what felt like a long time. I was monitored constantly. DD's heart rate kept dipping with contractions, but then came back up slowly. At some point, they were worried so took 2 samples of blood from her scalp. I was told what the level should be (not that I remember it now), the first reading was below and the 2nd one was at the minimum level. I was then left for another 2 hours before they did a section. I just wanted to know how serious DD's condition was I suppose. Not that it makes much difference now, just that I'd like to know incase (and thats a big incase!) I was ever in the same situation again.
