Hello. I have a quick question. I am on a generic Levora birth control pill, for nearly 3 years so I am fairly regulated on them. I skipped 3 pills due to hectic scheduling at work the week of 12/21 which is week 3 of my pack. I missed the pills for 12/22, 12/23, 12/24. I did not start withdrawal bleeding until 12/25. I bled from 12/25-1/1. I stopped bleeding 1/2 until about 11 pm (EST). I had very, very light pink spotting. I did have unprotected sex 12/24, which would be around the time of ovulation. My "normal" period (withdrawal) is usually Wednesday to Sunday. I should have started my placebos pills 12/28 and my withdrawal usually should have started 12/30 but I have been bleeding since 12/25. I plan to start my next pack 1/4. Should I be concerned with pregnancy?
