I missed my first two birth control pills this last month(janurary). I also had unprotected sex. I've been on this pill for 6 months or longer and I've always started 2 days earlier than the pills intend and it always lasts about 5 days. But this month(janurary) was different. I didnt start for 3 days after i usually do and it only lasted 3 days. It was light the first and last day but seemed normal the middle day, but not as heavy as normal. I've already started another pack of pills but pregnancy is still in the back of my mind. I dont want to waste my time or money on a test if i have nothing to worry about.
