Hello I recently finished my first month of Tri-Sprintec on Saturday and continued on my second pack Sunday and had unprotected sex. Ever since Sunday I've been burping frequently. I did intact have my menstrual cycle on te last week of my white pills. I went to plan parent hood and the doctor declined me from using the morning after pill she said I couldn't get pregnant since I was loyal to the pills. Instill feel insecure and unsure. I will take a pregnancy test bit I would like to get some feed back.
