In the male chart, both the the 5th lord Venus and the 5th cuspal lord Moon are in the 8th Bhava. Moon is aspected by Saturn and Rahu. Putra karaka Jupiter is in its debilitation house and aspected by Saturn. The Karaka Jupiter is located in Lagna itself. So, the 5th from it is the same as the 5th from Lagna.
In Saptamsa, both Lagna lord Moon and the 5th lord Mars occupy the 8th house. The duo is aspected by Saturn, the 8th lord. Rahu occupies Lagna. Karaka Jupiter does not aspect Lagna, Lagna lord, 5th house or 5th lord of Saptamsa.
In the female chart, the 5th Rasi of Karkataka and the 5th cuspal lord Saturn are both aspected by Rahu. The 5th lord Moon is in Kemdruma yoga, and aspected by the 8th lord Venus, the 12th lord Saturn and Ketu.
Lagna lord and dasa lord are both Jupiter. Jupiter is the lord of 22nd Drekkana and is aspected by Mars while Rahu joins it in Lagna. Jupiter is retrograde. Its nakshatra lord is Mercury who is in the 8th sign but the 7th bhava.
In Saptamsa, Lagna is aspected by retrograde Jupiter, Venus and Saturn. Venus is the lord of 22nd Drekkana while Jupiter and Venus both occupies a Sarpa Drekkana. The 5th house is aspected by Mars while the 5th lord Saturn is in the 12th to the 5th i.e the 4th house.
Considering all the above and considering the placement of Ketu in both the Rasi abd Drekkana charts, the probability of a second child is almost zero. Better not to put the female at the risk of more abortions.
