I stopped taking ortho tri cyclin lo on the 27th of June. I got my period on Aug 7, for the last 2 days I have had a yeast infection and when I went to use the medication I realized I was spotting is this normal?? I have been on bc on and off for 16 years. I have never had this happen! My period isn't due for 20days! I am ttc so could I be pregnant or is this just a side effect?
