Should I take another plan b?

So last Friday I had unprotected sex but he didn’t come inside of me. Regardless, immediately after he left I took a plan b like not even two hours after we had finished. It happened again on Monday, this time he came twice but not in me at all, like not even through pull out, just not inside me at all but it was still unprotected. It’s Wednesday now and I’m spotting from the first plan B I took but I’m still debating if I should take another one from the second time of doing it unprotected?? Idk, any feedback would be appreciated 🙃
