What Are The Chances Of Pregnancy When Having Menstrual Bleeding?

Embarrassing.. But here it goes so recently I had sex with two different guys back to back. The first one used a condom... That somehow got stuck inside of me... I didnt know and he didnt tell me because he was drunk.. Anywho the next day I hook up with a friend of mine from years ago... We um didnt use a condom... Oddly enough it didn't feel strange or anything.. So next day i am taking a shower while playing with my dildo and when i pull out my dildo a condom was stuck on it!!! Freak out central. And then today i got my period (this is a series of the past four days). I am making a womens wellness visit to get tested... However that isnt for another month... Should I still get a plan b even though my period started?
