Period after the pill

Nicole
I was on the pill for about 12 years and in May stopped because my husband and i wanted to try to get pregnant. My period didnt show for 3 months and after taking a pill my dr prescribed my period finally showed up last month. Earlier this week and I had some spotting and Aunt Flo showed up right on schedule but only for 1 day! I did take a pregnancy test 2 days prior to getting my period and it was negative. I'm not sure whether i should be concerned and go to my dr, or if this is normal or if I should take another pregnancy test. I don't want to worry over nothing but I also dont know what its like to have a normal cycle either! Any insight would be helpful!
