I am currently on my 2nd pack of birth control. Before taking the 2nd pack however, I have missed 2 pills in the beginning of my cycle. From then on, I took my birth control as usual schedule because I've experienced continuous spotting from taking more than 1 pill per day while taking the previous package of pills. After 6 days, I had unprotected sex. Having been with my boyfriend for several years, I am not stressing out too much about STDs . However, I'm slightly concerned about my chances of getting pregnant. Please help me out!
