Priyanka,
Currently you are running your Pisces which has absolutely no combinations for marriage.Your marriage will take place in your Aries chara dasha which will be running from 20/08/2018-18/06/2019 as it has very strong combinations for marriage.
If you make Aries which will be the dasha sign at that time as the Lagna you see that the 5th lord Sun goes into the seventh house which indicates love marriage but Sun is debilitated which will show difficulties in getting married.
Remedies:
1.Do Surya Namaskar every morning
2.Respect your Father
2.Chant Shukra beej mantra daily 108 times
God Bless,
Astrologer Akash.
