I've been birth control for 3 months now. I started my period last week Feb 7 and I stopped on Feb 12th. On Feb 14th and the 16th on boyfriend and I had unprocted sex. After we had sex Monday Feb 16th I stopped taking the pill. Today is Feb 20th in this morning I woke up to get ready for school in it showed a light pink when I wiped but I haven't had it happen since after that today. I seen my doctor yesterday for a check up on how the pill was doing an its been working fine. Now I'm worried why is it when I wiped this morning it was light pink. Could I be pregnant?
