hi, in addition to the other bits of advice offered here, you need to speak to your midwife, tell them you want to have a comprehensive discussion about birthing options, and that you want to see a consultant if needed (you would need their say so to be induced/csectioned).
i had terrible SPD and was wheelchair bound by 30 weeks and on huge amounts of painkillers. I fought a huge amount to get taken seriously by the consultant, and ended up only being listened to by the 3rd consultant i saw (i got the courage up after a while to ask to see a different person as i felt i wasnt being listened to). finally, when i was listened to i was given the options to either be induced at 37 weeks of csection at 39 (as i really wanted a csection as i too was scared shitless of a natural delivery). i was given these thoughts at 34 weeks and went back at 36 weeks with my decision.
as my pain had increased a huge amount in those 2 weeks i said i would (much prefer the induction at 37 weeks as if i had to go on for much longer i would need to move up to morphine for painkillers and that in itself was another risk to the baby.
so i went into the hospital at 37 weeks for induction. initially the dr on the ward that day didnt want to induce me, it was the first consultant i saw who i hated!, but after much insistance and a ultrasound the next day to check DDs size they started inducing me that afternoon.
they tried everything known to man to induce me, it took from the thursday when they started to induce me to the saturday evening and DD was eventually born by csection as the induction wasnt working much at all and DD wasnt happy in the womb at all.
mine is an extreme case, like i say i was wheelchair bound from 30weeks and on maximum dose of codeine from then too, so i had exhausted all sensible options of trying to get by until delivery!!
if you want to talk and get more opinions, hop on over to the SPD thread, there are lots of us on there.
im now just over 2 weeks post baby, i can now walk compeltely unaided again and im still just on the normal painkillers post csection. im still limited on movement and what i can do (not just from the csection), but the relief of being able to move about and turn over in bed with....only some difficulty is brilliant!
