After sharing an idea with many mfg's and individuals, it is being manufactured, what should I do?

I got a cool idea for an invention. I really wanted to see it developed even though I try to keep my ideas under wraps I couldn’t wait, I let this one out of the bag in hopes that it would see the light of day. Well, it did, and now many companies are building it suddenly.

Should I look into it, there are a few NDA’s involved.

I have other BIGGER ideas also…
