For the last year, I have rarely missed a pill, but have messed up the month of Aprils. I missed the last 3 days of my pack before my inactive week. UnfortunatelyI I did not research what I should have done until after the fact. The 3 days I missed were 11th, 12th, & the 13th. Started my period on the 15th, very light flow, 3 days long. Started the next pack on the 21st, Sunday, then missed a pill on the 23rd, doubled up the next day. Missed the 26th pill, doubled up the next day. Its now May 1st, & my cramps are already here. Not suppose to start until the 12th or so. My next OBGYN is in July & I will pursue a different method of birth control. My questions are ;how likely is pregnancy? What is the likely cause of these cramps? If pregnancy test is recommended, when is the recommended time to take one?
