Ortho Tricyclen Lo pregnancy risk?

Hello all,

After having been on Nuvaring for a couple of years I'm tired of the side effects, so I'm switching back to the pill. Before Nuvaring I was on Ortho Tricyclen, but this time they've given me Tricyclen Lo.

My boyfriend and I have been relying on the Nuvaring alone (i.e., no condoms or pull-out). But I have one friend, and I think a second mutual friend, who got pregnant on Tricyclen Lo. This is anecdotal, I know, but it's enough to give me pause.

Neither my boyfriend nor I are eager to start having to use condoms, but we're not thrilled with the idea of an oops either. If it makes any difference, I've always been good about taking my pills on time. Anyway, is there a greater risk with this particular pill?

Thanks for any help!

The CDC rates the patch, ring, mini-pills and regular HBC all as 7% "failure rate" with typical use. The NHS rates all of these similarly, as 99% effective (so 1% failure rate) with perfect use, 91% effective (so 9% failure rate) with typical use. Note that this means that out of 100 individuals using said method, they expect 1-9 to get pregnant over an entire year - so ≤9% chance for the year, not each use.

In particular, it sounds like you're concerned about the "Lo" part of your change? Nuvaring was a lower dose than this pill will be. If you're confident enough in the medication to have used Nuvaring without a backup method, and confident enough in your taking the pill around the same time each day to have used the pills before without a backup, this is no more risky than those. That said, there is always some risk, even with a backup method; you get to decide how much risk feels safe to you.
