Im currently 18 and my periods always been very irregular (long time periods without it and then get two or three in a very short time span, possibly a week inbetween) so my mom decided to put me on birth control to regulate me about 6 months ago. What ended up happening was it basically got rid of my period. Id only have it for 2 days and it was extremely light also in those 6 months ive only had it 4 times. When i told the doctor this she said it was normal, i am a dancer so i am in good shape and very active, also the pill does make it lighter, she didnt seem to concerned.

I have a boyfriend and we have recently become somewhat physical (not sex) although we can only see eachother once a week due to school. I hadnt had my period for a little over two months and then the day after we had hung out i got it. I figured it was just a coincidence but im starting to question that now, that was about a month ago. The last two times ive seen him ive had spotting after.. i dont know what this means or if it even means anything.. but im concerned.

What does this mean?
