Find a nearby airfield with an ILS if your aircraft is so equipped. Fly a few ILS approaches in VFR until you are 'competent'. If you get caught out above 8/8 clag, divert to said airfield, fly the ILS ( be prepared to explain if you are non- IR) and get a taxi home.
Don't fly below MSA in IMC unless you are qualified. Don't "scud run". It's not fun and you could kill yourself very easily!
If you expect conditions below 3-5miles vis/1500 cloud base - think "DO I REALLY WANT TO DO THIS?".
