Only take 1 plan b. Its dangerous to take anymore. Yes you can get pregnant even if he pulled out! And yes despite plan b you can still become pregnant. Plan b is like birth control there is still a failure rate its not 100% effective.
Dont take anymore plan b its not candy. Plan b has a certain percentage of working even when taking correctly an some people do get pregnant from precum so.....i doubt youll wind up pregnant but im just guessing.good luck!
You can get Prego with precum. But I think only 1 plan B is nessecary.
