Good luck for Friday. I had a surgical management for a MMC recently. Just to reassure you, it is a swift procedure, general anaesthetics have come on a long way and it really was just like dozing off.
Tips I wish I'd had:
Ask to take your oh in to hold your hand while they put you under if you are nervous (and that would help). I had to ask for this, they just assumed I'd be ok on my own and I wasn't.
A few hours prior to being put under I was given a pessary to soften my cervix - I wasn't prepared that they would ask me to put it in myself and for some reason found that quite upsetting but ultimately it was just like putting in a tampon. Not sure if things are different in other hospitals.... I had period like cramps an hour or so after and started to bleed so take do some pads with you just in case as you'll be waiting a few hours afterwards.
The hospital I went to asked me to change quite a long time before my slot on the waiting list. They gave me disposable knickers to wear under my pjs, which my pad didn't stick to, cue some embarrassed shuffling about. I wished I brought proper joggers to wear to give me some security and hold things in place.
The procedure itself felt like no time at all, I felt a bit groggy after. You'll be offered a drink and a biscuit and asked to have a wee before they will discharge you. I was a bit uncomfortable pain wise but (for me) nothing worse than period pains and totally manageable with standard painkillers - keep on top of these for the first few days and take care of yourself. You may find the emotion catches up with you the other side of the procedure. I think others people report feeling relief, it's v individual.
I experienced minimal bleeding post op, I think that varies. My period returned 6 weeks later but was very very light for the first two cycles - the third I got pregnant again
. So it can happen quickly.
Oh, and a few days post op I got quite uncomfortable trapped wind, which I gather is quite normal after this type of surgery. Took me a bit by surprise as I was back at work and wincing away in a meeting!
Best of luck. xx
