(Fatwa: 1531/1219=H/1430)
You should not go to any baba etc. This thing sometimes happens due to disorder in menstrual cycle and delay in marriage. Therefore, you should pay exclusive attention to same and consult any expert hakim. You should recite Surah Fatihah after every salah seven times with durood seven times before and after, and give your sister to drink. Also, ask your sister (patient) to recite the same, blow on her hands and spread over the body. She should do the same while going to bed in the state wudhu sitting on a clean bed, and pay attention to recite the duas of sleeping and waking up according to Sunnah.
