I'm also 32 weeks, and having similar issues. I was admitted into hospital at 27 weeks as I was having uncomfortable and regular tightenings. Cervix was closed, but fetal fibronectin test came back positive, so I had steroid injections for the baby's lungs if it came early. Things settled down, so was discharged after a couple of days.
Was then re-admitted with the same thing at 28 weeks.They examined me and said my cervix was shorter than they would have liked and I was about 1 cm dilated. Once again, things calmed down and I was discharged after a few days.
Was back in at 30 weeks with more tightenings, this time cervix was 2cm dilated. Was kept in hospital, and at 31 weeks I was still 2cm dilated so discharged.
I keep getting bouts of uncomfortable tightenings that come every 8-9 minutes for a couple of hours at a time, but they don't seem to really be doing anything! My consultant said to just lie down and rest when I get them, but call the hospital if they get more painful or go on for more than a couple of hours (or if waters go, any bleeding, etc.).
I also have a 2 year old DS, and am finding it nigh-on impossible to rest! I felt awful yesterday as he climbed up on my lap and sat on the top of my bump, which hurt like hell and started the tightenings off again. I shouted a bit, and he cried 
Poor little guy doesn't really understand any of this, and I couldn't help but shout, it was a reflex as it really hurt. I still feel awful, don't like making him cry.
I'm high risk for pre-term labour anyway. With DS I was admitted in pre-term labour at 33 weeks, was perfectly fine except contractions and I was dilating. At 33+6 weeks I suddenly developed pre-eclampsia, and DS finally came spontaneously the next day. From a gestation point of view, DS was fine. Didn't go to SCBU, came on the normal post-natal ward with me. He was 6lb though! We were in for a couple of days as they had to monitor his blood sugar, then discharged. He was re-admitted a week later as he had lost a lot of weight though, then we discovered he had no sucking reflex. He was tube-fed for a week, put weight back on, strengthened his suck and was then fine.
This has turned into an epic post, sorry about that! But basically, I'm in a similar situation, keep getting bouts of tightenings that fizzle into nothing. But, we're 32 weeks now, which is a great gestation! I've no experience of CS, but I think if you have an elective booked but go into labour before then they can still do a sort of emergency CS. Obviously, I don't know if there's a limit on gestation (i.e. if you're in labour at 34 weeks as opposed to a full-term 37), or if there's a point where labour is too far along for them to want to do the CS. Might be worth talking to you MW or obstetrician about what would happen in that case, hopefully to put your mind to rest.
