Some medicines do affect menses temporarily but not the ability to conceive. The effect on menses is reversed easily. There is no permanent effect on ability to conceive or menstruation cycle in the lifetime. In certain conditions
pregnant women have to continue their medications (antidepressants and/or antipsychotics) without danger to the fetus.
Next Steps
when starting these medicines do share your concerns with your doctor and they will give you clear information on risks vs benefits of these medicines on menses or pregnancy.
