I've been taking the pill for 1 month and two weeks now. I'm on the second week of the new pack but I took the 4th pill in the row 7 hours late. I usually take it around 10am but took it 5-6pm because I forgot. I had unprotected sex 2 days later in the morning around 9 am and my boyfriend ejaculated in me. Am I still protected or should I get Plan B?
