I'm On Birth Control N I'm A Sunday Starter! I

I'm on birth control n I'm a Sunday starter! I went out of town and left my birth control home on accident! When I got home it was around 3am Monday morning but I had sex around 11 or 12 Sunday night! When I got home I took my birth control pill but I didn't have the money for plan B! Would be ok because I took my birth control or do I have a problem on my hands
