I began taking a hormonal birth control pill Tarina Fe 1/20 in early January. I never intended to solely rely on the pill as my only form of birth control, but I got engaged in early March and things got carried away and we ended up deciding to have sex without a condom. I've been very good about taking my pills every day at around the same time. The day that intercourse occurred, I had just taken my first pill of my third pack, so it was my first active pill after my placebo week. I didn't think anything of it initially, but now I'm worried I should have taken plan B. I'm confused as to whether or not I am protected after coming off of seven days with no hormones. I bled the third day of the placebos until the sixth day (so Saturday-Tuesday) didn't bleed the last day I was on the placebos (Wednesday) and started my new pill pack on Thursday afternoon at my normal time. We had intercourse on Thursday night. Will that have given my body enough time to respond to the hormones in my active pill? Did I mess up by not taking Plan B? I tend to panic about pregnancy and that's why I got on the pill to begin with, so at the time I tried to be confident about my pill and it's effectiveness, but I've over thought it and now I'm mortified. Am I covered on the first day of my active pill pack after the placebo week?
