Raw sex but I’m on birth control pill

I had sex for the first time with this guy I’m seeing and it was completely raw, and included many times today. I finished lots of times as he was inside me and he finished twice, both times pulling out and having it land on my back and or thighs. Obviously there was probably pre-cum and or some cum probably inside me while messing around, I get that. I got off my period February 22nd and had sex February 24th. My period app explains I SHOULD be ovulating Saturday February 29th, kinda literally 5 days exactly from sleeping with him. I use birth control and take it exactly at 10:00pm every night but my worry is due to the fact it was raw on his part and even so, my birth control may not work. I don’t have the money to spend $50 on Plan B, and by this point I am having doubts that It’s actually necessary. I’m only concerned that I’m actually a bit concerned even though I’m taking my pill. Any pointers?
