Your life events are better connected with TOB 22-00
Here are my observations on your questions:
a)Request your inputs on married life and progeny prospects.Does my chart have kalasarpa yoga?
Married life is ok. Ven in 7H may give you a beautiful partner but its posited with Mars. Also in D-9 it is in mutual aspect with Mars, so she may be little agressive and short tempered.
b)Would my health tend to improve and become normal by end of Saturn dasha?
Health issues may continue as current dasha is Sat-Mars and Mars is 8L from Sat.
IN the next AD of Rahu, the situation may be same as Rahu is in 12H of hospitalization/foreign.
IN this dasha you may live abroad too.
c)How would Mercury dasha be? Would my career improve?Would I be able to work independently as a consultant?
Mer MD will start from Sept 2022
Mer is combust in 5H (within 2 deg of Sun). So you may observe that you're not getting whatever you deserve.
In D-10, Mer is 8L placed in 6H. So this time will be challenging in profession.
God bless you
