Hi - congratulations on your forthcoming marriage!
This is my first post on these forums, having been hanging around browsing for a while

but I finally feel I have something specific to offer.
I got married almost 3 months ago (hurray!), similarly intending to avoid pregnancy originally, having been charting using the
Billings method for a few months to get used to how it all worked. My husband and I were originally disappointed with a month or so to go to find that we were going to be fertile on the wedding day.
However, we talked about it and agreed that whether or not we had sex on the wedding night simply was not that important when compared to the rest of our lives together and we ended up waiting until pretty much the end of our 3 week honeymoon before consummating our marriage. [It was, however, slightly odd to go to mass the morning after the wedding, knowing that everyone probably thought we’d consummated the night before!]
But while it was quite difficult to wait (after waiting so long!) it didn’t in any way diminish how special the honeymoon was - we moved in together and spent 3 weeks focusing completely on each other, on what had changed between us when we got married, on how we were feeling apprehensive about having sex for the first time. Just lots and lots of real talking which made us really really close
I hope that’s helpful, anyway - I know you didn’t really ask for other people’s experiences, but I just wanted to let you know that abstaining on the honeymoon doesn’t spoil anything!
In terms of my answer to the poll, I plumped for the 3rd option as when I added it all up it probably works out about 15-18 days on average (I was actually surprised to find it was that long!). My cycles are usually about 28 days long and using the Billings method we usually have 3-6 days ‘unavailable’ for lovemaking during my period, then a few ‘available’, then 10-14 days ‘unavailable’ while I’m fertile before about 7 days of infertility before my next period. So we usually have more days of abstaining than not at the moment, but we’re enjoying it when we can
