Heomarrage after c/s - will it happen again?

Hi everyone

Not sure if I have posted this in the wrong place or not....

Well a bit of background....

I went 10 days over with DS1 in 2005, was induced and ended up with an emergency cs. No complications from the surgery at all.

Chose an elective cs in 2007 for DS2 at 39 weeks. All went well until I started to heomarrage in recovery. Bleeding was stopped relatively quickly (the staff were amazing) and all up I lost only around 700mls blood.

Anyway, we are now thinking of TTC but I want to do a bit of research on heomarrahges and the common-ness with which it may happen again.

Does anyone have any stories they would like to share, or some good links etc to some good info?

Is it just 'one of those things' or does having one increase your risk of another?

TIA
