I take sprintec 28 day continually and have my period every 3 mo. My lmp was the begining of January. I missed a pill the begining of February and doubled up the nxt day same time I started spotting end of February so I stopped my pill the 18th-22nd and had a period. Started a new pack the 23rd and have taken it correctly, my bf and I had unprotected sex the 23rd and the 27th and he did ejaculate inside of me. Should I be protected from pregnancy??
