Is it worth going to buy the morning after pill?

[Ride4Life]

Tonight, I had sex with my new boyfriend. We used a condom, but then we had sex again, and instead of putting another condom on, he just pulled out. I'm usually not "okay" with doing that, but I don't know what was going through my head honestly. I'm not that young (I'm 21) and it's not my first time having sex at all, just now I feel slightly worried. Like I know that pulling out is not foolproof, so would it be a good idea to get the morning after pill tomorrow? I don't think I would make the hours at the planned parenthood clinic tomorrow, so I would have to go to CVS, does anyone know how expensive it would be roughly? I'm a student who's a little short on cash. I'm not on birth control right now, but I plan to be soon, I have to schedule an appointment. Thanks. I know that what happened tonight really wasn't the best scenario, but I don't really feel like "waiting" around in a few weeks to see if my period comes and stress out over it. I rather take the pill or pills and feel better about the situation. Trust me, I'm not going to let that happen again.
