Ok i have been on bc for a lil over a year.. I was on ortho cyclen for a year and my doc changed it because i was having terrible headaches. She switched me to ortho tri cyclen (lower dose) well im on my 3rd pack of them and i ALWAYS miss atleast one pill out the pack sometimes more.. (i have a 2 1/2 year old that takes up my time lol) but here is my question i am a sunday starter and i missed my pills on the 25th and 26th but doubled up on the 27th. I had unprotected sex the 24th, 25th, and 26th. I take my first non hormonal pill this coming sunday. What are my chances?
