Took birth control 4 hours late (for the first time)

I always take my birth control (Tri Lo Marzia, a combination pill) at 6am. This time my alarm didn't go off and I ended up taking it at 10:30am. My partner and I just had sex (twice, no back up method for once) yesterday as well. How much more has my risk of pregnancy gone up?? I'm actually worried 😅
