finasteride and risk of pregnancy

I am using finasteride and me and my partner had unprotected sex whilst she was in her infertile stage of the menstrual cycle. This may sound stupid but I am worried that having unprotected sex whilst on finasteride will cause damage to the female’s reproductive ability / any egg cells. Is use of a condom specifically recommended if your partner is pregnant or could get pregnant? We are not looking to have children for another few years at which point I will quit using finasteride but just worrying myself that there will be damage caused by unprotected sex in the present

If you are using any birth control, not a problem. The use of a condom is recommended if she it tying to get pregnant. Timing fertility (the actual point of ovulation by taking body temperatures) is not always accurate unless she is regular on her periods.
