I started having irregular cycles around may -June . I went to the doctor and she put me on sprintec . She told me to take it for 3 months to regulate my cycle . October and November were my first months I had regular cycles without being on birth control . Now it's December and my cycle is 17 days late . I was sexually active the day before and the day my cycle was suppose to start . I did take a pregnancy test around 5 to 7 days late and it was negative . I'm having light cramping as if I'm going to start my cycle but that has been happening for the past 10 days on and off . I'm also experiencing very white And stretchy cervical mucus . I'm very confused on what could be going on at this point . Should I take another test ? Could it be my body reacting to not being on the birth control ?
