I Have Been On The Pill For 15 Yrs. My

I have been on the pill for 15 yrs. My period has always been pretty regular on it. Start on a Tuesday and ends on a Wed night. But this month. I started about 1 pm Tuesday and by 7pm I wasnt bleeding. It was also extremely light. Then on Wed it started again for about an 1hr. And again extremely light. So I was wondering the possibilities for why this happened. Also my boyfriend has been saying that I haven't been getting wet during sex even though I know I am aroused. I was trying to figure out reasons for that. Could it be the pill or me getting older or what? Thank you
