I got my period on June 3rd (Sunday) and it was normal lasted like 4-5 days... I always seem to get my period the 1st Sunday of the month... well I had sex around the 16 or 17th... well than I got my period the 30 so a Saturday and a day early and it seemed normal... I went to the doctor on July 7th because I had a urinary tract infection and they did a pregnancy test and it came out negative... so if I got my period last day of June going into July will I still get one the end of July? I'm afraid I might be pregnant...
