What are the chances of conceiving when you and your partner take his?

The chances of conceiving when you and your partner take his are highly dependent on various factors, including your partner's situation and any medication they may be taking. It's important to note that hormonal birth control, such as birth control pills, patches, or injections, are highly effective in preventing pregnancy when used correctly and consistently. If your partner is taking hormonal birth control, the chances of pregnancy while they are taking it are low.

Some hormonal contraceptives, such as certain types of birth control pills, may have a brief period after they are stopped during which fertility may be increased. This is known as the rebound effect, but its occurrence and magnitude can vary.

If your partner is not taking any hormonal contraception or has stopped using them and you are having unprotected sex, then the chances of conception depend on the timing of sex relative to your menstrual cycle and other factors affecting fertility. Ovulation usually occurs around day 14 of a 28-day menstrual cycle, but this can vary from person to person. The most fertile days are the days leading up to and including ovulation.

Overall, the chances of conception when your partner takes his depend on various factors, and it's essential to consider your partner's situation and medical history. It's always best to consult with a healthcare professional or a fertility specialist if you have specific questions or concerns about conceiving.
