Hi Shinyshilling
I had SPD with dd's preg - she's now 5 months old.
I'd had an emergency section with ds so was really keen to avoid a section again. Consultant wasn't that convinced I'd get a normal delivery this time round, but I was desperate to at least try.
When I was in labour I made sure the m/w and other staff were totally aware of the fact I had SPD and they were brilliant. Every time I was examined by a doctor (loads of monitoring cos of previous section, not SPD) the m/w would jump down their throats and say - "NOOOOO don't split her THAT far apart - don't you know she's got terrible PUBIC pain". I always hated that word!
Anyway, long story short-ish. Dd was in distress (as ds had been at the same stage) so I was advised to have an epidural just in case I need a section, plus dd was back to back and pushing was an evil experience.
I'd been told by my physio to avoid an epidural if at all possible cos that's when permanent damage can happen - you don't feel a thing and your legs flop too far and split. So the m/w again was v v careful to make sure my legs didn't go further than they'd been able to pre-epidural IYSWIM.
Pushed dd out in 45 mins - don't know if that's fast or slow tbh. She was 8lbs 7oz with average head size.
Pain was immense afterwards and is only disappearing now after 5 months. It's very sore the day after sex too
Just make sure your m/w is informed and your birth partner too so they can keep an eye on your legs
You will be slightly limited in birth positions, but your physio will recommend the best one's for you. And remember that pain relief will mask the pelvic pain too so don't get carried away!
good luck!
