If you're feeling ok in general (no high temp, pain that can easily be sorted with panadol etc) you should be ok hon. I was told when I had mine that bleeding is ok as long as it's not flooding a pad every hour. Heavier than that definitely get it checked out.
I also noticed with mine that immediately upon having it done blood loss was minimal but it came on heavier after a few days, then sort of did this stop-start-stop-start thing for nearly 3 weeks. Every time I thought it was gone - voila, it was back. My GP said this too is normal but not to have intercourse at all while you are bleeding, as everything is still slightly 'open' and infection could be introduced.
If you are worried at any stage though hon - head off to your GP or the ED if it's after hours
ETA: Re: Pain relief...I was on panadol for almost a week. For me the cramping and backache seemed worse a few days afterwards, so I wasn't afraid to take pills if I needed them. Also, I had one episode of incontinence after the D&C - I reckon it was maybe 3 days afterwards? The GP said it was due to all the internal trauma of the surgery and this too was normal. I'm pleased to report that resolved itself quite quickly.
