Fantastic news honey I remember getting that stat myself at 7 weeks, after a threatened MC. Amazing isn't it!
Hang around this thread too much though and we'll have you delivering your baybee with just you and your OH, in a field full of butterflies with lavender oil and homeopathy to relax you so you don't need DRUGS.
In all seriousness, your choice is entirely yours but ensure that you are completely up to speed with the pros and cons of pain relief. While the idea of giving birth without pain sounds great, actually we have yet to invent pain relief which doesn't have side effects - sometimes not a problem, sometimes leading to proper problems. Be aware of your options and make an informed decision.
There's no merit or martyrdom in pain as such. But there is merit in doing your best to ensure that both you and your baby are both physically and mentally healthy after the birth - contrary to what you'll get a lot of on MN, it's not all just about having a healthy baby - a healthy baby and a damaged mum (mentally or physically) is really bad news. Obviously. Pain relief which leads to forceps for instance could leave you with damage and in physical pain for months or more.
I have my personal opinions on what is right for me, however I have the added advantage of having already given birth without intervention or pain relief (other than a TENS which was fantastic). I am NOT telling you that you need to give birth without anything or that I am better than someone who chooses drugs. I happened to have a number of advantages. The main ones were my mum as a doula (retired midwife) through the whole labour, so I was always able to be relaxed and leave the decisions to someone else I trusted, and contractions which happened to be in the cycle of one strong, one weak, giving me the chance to recover. Despite my labour being back to back which usually leads to long and painful labours, my mum encouraged me to get into the right positions to get him turned properly. Being left in a hospital bed, not being able to move, strapped to an epidural and without someone with me all the time (as is typical in a hospital birth) he would never had turned and I'd have either been Em CS or forceps.
A friend of mine was determined to go for an El CS but in the end decided not to, and it all went wrong - it clearly showed that an absolute embargo on interventions is not the right thing to do. I'm just trying to say, don't be afraid to go drug-free, it really is ok, or at least keep your options open, and at the VERY least be totally informed on what different drugs will do to you and your baby and make a decision based on what you feel you're happy with.
After all, many women swear by epidurals and have had straightforward and relatively pain-free labours with them, with no subsequent problems... so who am I to say that's not the way to go.
