Hi, I have been taking birth control for the last 3 years, starting with Loestrin 24 Fe in 2012, then switching to Trinessa at the end of 2013, and finally switching to Minastrin 24 Fe in June of this year. I am currently on my 3rd week of my first Minastrin pack and I ve been cramping and spotting for the last 3 days. When switching to Minastrin, I took the first active pill the day after I took my last inactive pill from my Trinessa pack. My boyfriend and I always have unprotected sex and I NEVER miss a pill and always take my pill at the same time every day. I m worried I may be pregnant because of the spotting and cramping, is this very likely? I m supposed to have my first period from the Minastrin pack at the end of next week
