Missed period after stopping Ortho Tri-Cyclen Lo?

I was on birth control pills for 5 years, and recently decided to stop and give my body a break. I had fairly recent periods the first 3 months (my cycles were 37, 38, and 32 days long) but I am currently at 62 days! Basically, I missed my period last month all together. I took 3 negative home pregnancy tests, and 1 negative clinical pregnancy test with my doc. Doc says she's almost certain I'm not pregnant at this point, and my cycle is probably still getting back on track. She even recommended that I just get back on B.C. to force a period, but that is the last thing I want to do considering B.C. is the reason for all this irregularity (presumably!) Anyway, I've read that your first few periods could still be so-called fake, and that I could just now being trying to really ovulate... but I guess I was just hoping to hear form anyone else who has had this problem and overcame it? Thanks!
