Taking Plan B two times in 2 months

I took plan B in December because I had anxiety.. When I look back it was for no reason but now I have a reason. Me and BF had sex and the condom broke and he cummed. I used spermicide Today Sponge(anyone use this) but it's all flipped. So Idk if it worked.  But now I have to take plan B AGAIN. I'm so scared.
