Hello. I've been on birth control for a month and a week now. Two nights ago I arrived home from college and realized I left my pills at school. The next morning I went to the doctor and got prescribed another pack. Since I take the pill at 8 pm, I missed one pill. I took it at 11 am the next morning when I got a new pack. The new pack is Junel 1/20 fe, whereas my old pack was Tarina 1/20 fe. Are these the same? Can I continue the new pack on the day I left off on my old pack? Also I had sex without a condom and without withdrawal the morning before leaving school (so, on the same day that I did not take a pill at night when I usually do). Should I be concerned? This was now 2 days ago.

Thank you in advance.
