Lochia question (TMI alert!)

[MrsMopple]

I am nearly 7 weeks post delivery, but it was a section at 34 weeks and a twin pregnancy (not sure if that's relevant!). My lochia was quite heavy and prolonged, but tailed off to a pinky discharge. There is still a bit of discharge and when I see it (on toilet paper) it has a slight greenish tinge which worries me a bit.
But a more worrying thing is, this morning I noticed a quite strong and quite unpleasant smell when I went to the loo, which was coming from the pant liner I had been wearing overnight. Very hard to describe the smell, as it's unlike anything I've smelt before but almost yeasty. I have noticed it throughout today, too. I have my post partum check on Tuesday, but wondered whether I should see a GP tomorrow in case there's anything awful happening internally.
Any ideas what it could be and would you go to the GP tomorrow or wait until Tuesday?

With a smell I'd go tomorrow and ask for a swab incase of infection. Do you have a temperature at all?

No temperature, and I feel absolutely fine apart from the usual lack of sleep tiredness that goes with newborn babies.

The only stupid thing I have done is lift up my eldest child a few weeks back, which tugged at my internal stomach wounds a bit and hurt for a few days afterwards. I'm wondering whether I could have caused a problem then.

And stupid question, but how would I get an infection so far after the c section? (There hasn't been any activity in that area since the birth!)

you haven't eaten asparagus have you? [hopeful straw]

Thanks drinkyourmilk, but no, it's not asparagus. I always think that asparagus wee smells like burnt dust!

I'm off to bed, so won't be back on until morning, but advice / suggestions welcomed!

I would go sooner rather than later. You have 2 of the things that they tell you to go to GP for. I can't remember what the others are mind you!

Went to the GP who said it sounded like there could be retained products and gave me some antibiotics and has referred me for a scan to see if there has been anything left behind. If there isn't anything on the scan and I still have the issue after the antibiotics then they'll do swabs etc.
