Fertility Help

[extrashot]

I have pregnancy set on menstrual cycle and the only time there is any pregnancy chance is on the fertile window day. Any other day the chance of pregnancy is 0%. I've tested with short or long menstrual cycles, I've tested with or without birth control, I've tested with unreliable birth control. This is any sim, with no conflict like dislikes children. If it's vaginal I always get the notification that there's a chance of pregnancy, even if there's 0% chance.

 

I'm just wondering if there's a setting I'm missing. I don't want only one day with any chance of pregnancy, or to need to do fertility treatment for each baby. The chances didn't used to be 0%, this changed at some point, maybe with that last big update a couple months ago? I haven't been playing enough to notice until now. Thanks in advance.
