Your Ketu rules at a time when you used to go to school. Does this mean that when you got married you used to live in time already? Was not it the beginner yet? Even the menstrual cycle had to wait for some years.
Regarding Saturn's house - one site generating birth chart with 329.13 deg (7th house), another site generating 330.52 deg (8th house) and this is at the border (cusp) of 2 rasis. In this case you have to confirm your saturn's house by reading the 2 links and decide which suits you

- Sat in Pisces (8th H) - https://www.indastro.com/planet-sign/saturn-pisces.html
(you can google for Sat in Aq and Sat in Ps).
