i m 27years old, 22weeks pregnant, its my first pregnancy. i used primolut N 5mg in 2009 to delay menstraution. after stop using it, i had my normal periods but after 1 month i experienced itching around vagina and vulva , it becomes more at night times and usually not occur during day timings. i used a herbal medicated oil to cure it. it lessen usually the problem, then i experienced a vaginal discharge that also causes burning and itching around outside the vagina and vulva, for this i used the same oil. in 2009, the problem vanished after sometime but again in 2010 during rainy season, re appears, i used the same oil, it lessen the problem again. in 2011 the problem vanishes upto 75%, and what i have noticed is the change of water which i used to clean my sanitory need. i also used hair removing cream. the water which i used previously for sanitory purpose is from the well, the hard water, in 2012 i got married and the problem of itching is almost over nearlly 95% but still had a minor burning problem around vagina that is outside and of labia minora but it happens sometimes and vanishes itself within a minute. this minor burning is associated with the little vaginal dicharge. i have told this to my gynae doctor, she has done a test, and the result is normal. she said she thinks its normal because the color, consistency odour of discharge is normal, and the ultrasound reports which are doing during pregnancy are all normal. so what is the most probable reason for this kind of minor burning after vagianal dicharge that occurs sometimes with the discharge not with every discharge?
