I'm on birth control (Junel Fe 120). The last time I had sexual intercourse was July 11. I had to stop taking birth control around July 7 because I finished a pack, but couldn't get a new pack due to a backup on my insurance. I was off the pill for a month. I had 2 cycles since then. One very heavy like it was before I got on the pill, then one light because I started taking the pill again. I'm 8 days late on my period this month and I don't know why. I've been taking my pills regularly, however I stopped on September 24, due to another holdup at my insurance office, and I finished the pack but couldn't get a new one. I just want to gain answers as to why my period is late, and if I should be worried I'll be 19 in about 2 weeks.
