Need some advice

Well I'm on the pill and I have two kids with my husband (boy 6yrs girl 20 months) we own our home he works a steady job we're good but I made up my mind after my second child that's I didn't want anymore so I got on the pill well now for about a month now I've been thinking about having another baby so I need know y'all opinions I mean the only reason I don't want another one is because I like to go out sometimes have fun I'm young 26 years old but I also think if I have a third child I would go ahead and get my tubes tied after giving birth ..
