About 2 months ago, I went off of my Ortho Tri-cyclen Lo. I lost my insurance and can't afford it right now. Even when I was on BC I used a condom every single time. Last month was the first month off of BC and I got my period on time and it was normal. This month, I still haven't gotten it. I use protection EVERY time and make sure we check to make sure nothing went wrong as I am paranoid about stuff like this. I was just wondering if this is normal when coming off of BC where you can get it one month on time, and then not the second, and so on. Thanks so much.
