Depo shot versus plan b

Okay so, I have these 2 guys I've been going back and forth with, and I got off my period on the 26th of April, and the day after (27th of April) I took a pregnancy test, so I can get on the depo shot. Then the next day (the 28th) I reviewed the depo shot, as to what I researched it takes 24 hours for the pill to take affect. So Saturday (30th of April) me and one of my dudes has sex, he came inside of me. As to today, the other guy came inside of me too. Am I safe or no? Please say yes! 😭😭
