I take desogestrel and have done for nearly 5 years. I have been sexually active for all 5 of those years and didn't wear condoms nor did my partner pull out. I have not fallen pregnant once and I'm really not great at remembering to take my pill, sometimes I'll take it in the evening instead of the morning or even the next day. Not saying that your feelings aren't valid, because I used to get very scared about falling pregnant in the beginning. Aslong as you are as diligent in taking the pill as you seem to be it should be okay.

The pill is 99.9% effective, me and my partner go unprotected and we have never had any scares or problems. I was nervous in the beginning too, and I did have some anxiety and nausea the first time we did it due to worries, but it's been a few months now and I've never had any issues, even with missed pills every now and then
