Employee Pension Scheme

Hello. I was auto-enrolled onto the pension scheme at my civil service job which lasts 3 months.

As this is my first job in many years, and my previous jobs a long time ago did not enroll me on any pension scheme, and because I don’t know when my next job might be or if they will have a pension scheme, would it be better if I take the money instead of paying into the pension scheme?

Also, can I take out the money already paid into the pension scheme in the first month and have it paid into my next salary pay for the following month if I opt out of the pension scheme?

Thanks.
