Help please!

So my boyfriend and I had unprotected sex the other day and I got the plan b pill afterwards . An hour later we had sex again and he came inside me again. I'm not very active with logging on my glow chart but it said I was ovulating. So I'm scared my might be pregnant. I don't know if the pill covered the second time we had sex even though I took the pill the same day. Please help if this has happened to anyone else!
