May or may not be pregnant

Update I got my period around 9pm tonight thank y’all so much!! 🙏🏻

Okay so I’ve been on birth control (pill) for a year and half now I have recently started having sex without a condom but he pulls out every time. I take my birth control between a 10pm-12am time frame but usually take it around 10:30. On April 23, my boyfriend and I were having sex and he came in me. I wasn’t mad not scared because I take it regularly and on time and I’ve been on birth control for over a year now. My period is supposed to come this week and it’s usually here on Tuesday or Wednesday but today’s Wednesday and it’s not here yet. Now I’m kind of freaking out. Plus I just finished all my college finals yesterday so I’ve been pretty stressed. If my period doesn’t come in the next couple of days I’m going to test but should I be worried about being pregnant or could it be just the stress? Thank you all so much I really would appreciate some peace of mind! 🙏🏻
