I've been with my husband for over 9 years now and we've never used condoms or birth control. We've strictly used the withdrawal method and have never had any accidents or pregnancy scares. I know that this method isn't nearly considered effective, but it has worked beautifully for us.
We conceived our two children, and the pregnancy in which we miscarried, within the first cycle, so I assumed it would be that easy this time around. But no, we are in our third cycle now. It's frustrating to me because I am used to little to no effort. I'm not used to having to rely on OPKs and charting, but I know that 3 months is still very early on for a lot of couples.
I'm just now entering my fertile week so lots of BDing is in store for us.
Best of luck!
