Pregnant or not?

So yesterday I started my period and I had intercourse with my boyfriend(unprotected). I know not the best idea but I’ve been taking birth control(the pill) and everything we read on Google before hand and even he told me that because I was on my period as well as birth control I would be fine and nothing is likely to happen to me. He said that since I’m bleeding, the sun will just come back out anyways and my eve app said I had only a 1% chance of getting pregnant. I believe him and I trust him but he came inside of me and I then pushed it out right after just to see. I don’t really think I have anything I should be worried about but I haven’t stopped thinking about it. Any advise or can anyone please help me out and tell me if I should be worried or not?
