Ah the first poo. I obviously hadn't done my homework and hen the nurse said afterwards "don't be afraid to poo" I thought "why the hell would I be afraid? Ive just had a baby come out...how bad can a little poo be?"
Three days and many attempts later I finally managed it. It was agony. Like a brick.
Baby#2 I was prepared: I made lots of oatmeal & dried apricot biscuits: oatmeal to get the milk in, apricots for iron (blood loss) and fibre. No issues pooing at all. Mind you, he came out more easily: #1 was ventouse and episiotomy.
I was shocked at the lochia. I thought one pack of pads would be plenty hahaha. Try one pack A DAY. Plus some pampers care mats to go under you for when they leak. For the first week. Though with #2 I had a retained placenta and they cleared me out in surgery so a lot less second time round.
Make sure you take it easy. I was determined to carry on like nothing had happened. After about 2 weeks I started bleeding again, fresh blood, as I was doing too much.
Sex....first time we did it after (post 6 week check) I cried as I couldn't feel a thing. That improved over time though.
Long term damage was a cystocele which I have decided to live with as I'm not really incontinent and can manage (though trampolining or sneezing while walking is out) and a rectocele which I had repaired 4 years later. The surgery hurt like buggery (literally) but I'm good now: can poo normally and go for a run without feeling like I'm going to shit myself. Very glad I did that.
Don't believe people who tell you if you Kegel the crap out of things your pelvic floor will heal/not be damaged. You may avoid damage....but luck has a bigger role to play. Kegels cant fix serious pelvic floor damage and mangled tissues. Nobody tells you an abdominal hernia will fix itself if only you did enough sit ups, and I just don't see why this is really any different. They might help a bit so by all means do them (and I do) but they are not magic.
Push your GP for referral for surgery if you are prolapsed. There's this weird attitude "yeah it happens....live with it" but many times it can be fixed.
