Should I take Another plan b!?

So Monday night, my bf cummed inside me, so I took a plan b yesterday morning ( Tuesday ). Well that same night we had sex and he came inside me againnnn after I told him not too 😑😩 Cause I had just tooken that plan b pill that morning! Should I take another plan b ? Or will my plan b from the morning cover me still?

-Edit- ladies. Thanks for letting me know that plan b is not a form a birth control. I GET IT. We DO use protected sex but it was BY ACCIDENT the first time I needed to take it . this is only my second time ever taking a plan b. and I know that getting on birth control is cheaper. Because plan B is expensive af. But, I didn’t come on here to be lectured. I came here so you ladies can help me answer my question!!! Not lecture me.
