In 2019 2nd half there are chances.
Mars dosha:
If Mars is in 1 or 2 or 4 or 7 or 8 or 12 houses either from Venus, Moon or Lagna it is said to be Mars dosha.
In your case Mars is in 4th house from Moon, which is said to be Mars dosha and is evil. There is no dosha being in 5th from lagna, 3rd from Venus.
But the evil effect will be warded off as it it in its own sign Mesha. Hence you are free from Mars dosha.
