I will never forget what my labour pains were like! I don't get the idea that you magically 'forget' the pain in a way that's different to any other painful experience you go through. After all, if I try and remember what it was like to have an abscess, I can't summon up the exact experience so I'm rolling about in agony just from the memory but I absolutely remember what I went through!
For me it's been the same with childbirth and after the second time, I really think I deserve a blinking medal for first time round. However, I did volunteer to do it again after DC1(and I would have a third in a heartbeat!) so it obviously didn't put me off, though it was more the thought that it's half a day of pain (not bad for a first timer, I know!) for an amazing end result.
First labour was all in my back and I was 7cm dilated in less than 2 hours from my first contraction so it was rather like being hit by a bus.It was pretty intense and quite frankly I felt like I was being electrocuted up my spine - the base of my skull was shuddering with each contraction. However...on a scale of 1-10 where 10 is 'please shoot me' I reckoned I was only 8.5 or 9, it never got to the point I couldn't cope with it. Had paracetamol, G&A and was in the pool.
Second stage not so great, 3 hours of pushing before I was given a spinal block for forceps but you are pushing into the pain which helps counteract it to some extent. Was delighted to see the anaethetist though....!
With DC2, it was totally different. I was only 32 weeks pregnant and had what I thought was just a bad stomach bug for 48 hours
. Realised my waters were leaking so went in to get checked, was on a monitor and dozing less than 2 hours before DC2 made his appearance. I was giving it "I'm not in labour, this is not nearly sore enough for labour" to the midwives (turned out I was 6cm by this point!).
I was refusing G&A as I thought it was going to be a long night and I didn't want to start on it too soon....then the pain ramped right up. 20 minutes, lots of G&A and DC2 was out.
Though crowning was a surprise to me (anaesthetic/forceps previously)and I suddenly thought "OMG I'm at 11! I'm at 11! ELEVEN!!!!!!" (using previous pain scale of 1-10).Not helped by midwife saying "that's NOW the head" and I was thinking she'd said "that's NOT the head" and which sent me into a total panic as I was thinking I couldn't take 3 hours of that much pain. DH says my face was a picture - felt like either my undercarriage or my eyeballs would burst and wasn't sure which would go first!
I really believe there is no such thing as different pain thresholds, but there are different types of pain. Be open minded on the day, worrying about it before will not reduce the pain at the time.
