Madam
There is no dosha in your chart. It is almost correct.
In your chart, Saturn is sub lord of 1st, 2nd, 4th, 6th, 7th, 8th and 12th houses. Saturn is in the star of Moon in 7th house. Saturn is in the sub of Mercury in 11th house aspected by Moon and Mars. Moon is in the star of Saturn. Moon progresses too fast and Saturn pulls down. Moon is the indicator of mind.
So there would always be mental tensions in your life. Without delays and postponements you can not finish any task. It may be in your education or domestic front. There would be tensions from others with whom you deal.
Now present dasa is of Venus which is upto 27-9-2040. In it Sun bhukti is upto 27-1-2025. Venus is in the star of Ketu and Ketu is in 6th house – health issues. Venus is in 12th house – long distance travels, hospitals
Sun bhukti is upto 27-1-2025. Sun is in 10th house and sun signifies 3rd and 9th house. In this Saturn antara is upto 15-9-2024. So in this period you have to visit hospitals in connection with some illness. Next antara is Mercury it is in 11th house. So you will have cure and be happy.
Good Luck
