My last period was May 15th, but only lasted one day, started as normal flow and then light within several hours and was completely done before even 24 hours. Then as of 6/17/12 I took a pregnancy test which came back positive, could my last period have been spotting ? I ve made an appointment to a doctor to find out how far along I am, but trying to make sure that May 15th was indeed my last period, or if April 12th was my last period.
