I was pressured into having a restraining order against my boyfriend after domestics violence by social services , since then we have been having sex and I have court pregnant social services are no longer involved if I was to keep baby would they find out and would I be able to life the order without them knowing

You either have the order or you broke the order. You can't re-enforce an order at your will that you broke. So if they find you are back with him they can do what they deem necessary depending on the situation.
