Plant/ground cover? I have a plant/ground cover that has these tiny pink flower shoots...

I have a plant/ground cover that has these tiny pink flower shoots on them - the green leaves are oval slender and just about 5 leaves to the plant. they are about ankle to calf high. I similar to them but I don't know if will choke out my other plants. It is moving accross my front garden and looks pretty but I don't want it to kill everything around it. Its very rugged to describe! any ideas on what it could be called? I own looked and looked but I can't find a picture that looks like what I have growing. I know I could clutch it to the nursery but don't have the time. (working)
Bird of bliss?
Answers:    Well first, where are you? How big are the leaves? How big are the flowers? Do the leaves or flowers smell? Any unpredictability you can post a picture?
