I'm super paranoid I'll end up knocked up and I'm just wondering if I take my combination pill at different times every day will I still be protected against pregnancy? a few weeks ago I took it at 4 pm one day then 2 pm the next as opposed to my usual 7 am and I was wondering if I would still be protected. I came into contact with some semen on my vagina 3-4 days later and now its around 10 days later and I feel a little crampy in my lower abdomen. any chance thats IB? Super nervous as I am only 16! help!
