Am safe to have sex after taking pill irregularly?

Patient: I travelled to different time zone last week (7 hours ahead) and started my monthly birthcontrol pill cycle (pill called Levora) on the Day1 of travel. I took it every morning ~9am in traveling timezone. When I came back (Day 8), I took the pill at 6pm ET (1am of next day in travelling timezone: 15 hrs later than normal). I have then been taking the pill at 7am ET every morning (2pm in traveling timezone). I got my period on Day10 of my cycle. Is now Day12 and am still taking pill. Am I safe to have sex?

Symptoms: No symptoms
