I'm taking Nortrel 7 7 7 28 for birth control. I am on my second month. I'm a little concerned about if I am protected from pregnancy or not? I had my period 3/19-3/23 and started the new pack on the 24th. We had sex on the 25th and he didn't pull out completely. I'm now 4 days in to the 2nd week pills and my breasts are tender and sore. I'm trying not to freak out because I know that can also be a side effect of the pill. I haven't missed a pill since I've started the pill and have always taken them within an hour 10-11 AM. Should I be protected?
