No problem! ^_^
Given that you are wearing a slave bracelet, such attempts would not really work, there are simply things you can't do, and escaping is one of them. You are sold "legally" even if the way they trapped you is a scam, so escaping would mean nothing anyway.
The pregnancy system is implemented manually, meaning I add to individual scenes the required calls if I think they should have the potential for pregnancy (this is for obvious reasons, since as you point out there is lesbian sex as well as other acts that won't end with a baby). Sometimes, I might even "hold back" and not have all the possible scenes with a character flagged, because I want to make sure you have reached a certain point in their path before making it possible (to avoid weird edge cases where we have a named NPC, but you don't really know how to get in touch with them and stuff like that if you decide to retire, for example).
Maybe I'll add an option in the prayers to toggle a notification for the conception. It should be easy enough to have the notification, now I just have to decide if I want something to appear visually or if it's enough to have a sound and a message.
