The fertile period and signs of a fresh conception

Experts call the ten days (nights) from the appearance of menstruation the ritukala; some hold it can exist without visible menstruation, and some count sixteen nights. A woman who has just conceived shows languor, fatigue, exhaustion, thirst and movement in the abdomen. A footnote defines ritukala as the time fit for conception and calls intercourse after it blameworthy, since it does not lead to conception.
