Fluid dripped down my leg and on the inside of me during intercourse as soon as he pulled out. we checked the condom and it was fine. should i worry?

Probably not: If your condom did not break and you dont think it was semen in the fluid, then you may be ok. I would recommend being on a reliable form of birth control. Even with regular perfect use, condoms are prone to failure and have a 10-15% failure rate. If you want to lower your chances of being pregnant, you can also take plan B to give you some relief.
