Hi, I am on lo loestrin fe and i have been on it continuously for about two years and on the birth control I stopped getting my period. On Sunday I was sick and threw up for a while but it was later in the day at least 6 hours after i took my birth control pill. The next day I had vaginal spotting/bleeding and still took my dose at the normal time. It has been three days and I am still lightly spotting. Is there a problem or something I can do?
