Are you looking for the right gynaecologist in Delhi it may take some time?
To find the Best of something is not very easy but it is not so difficult also. Try to find someone with whom you feel you can be comfortable with, and with whom you can talk frankly as many times you need a Gynaecologist for discussing very personal things.
Your gynaecologist will also be the one helping you through your pregnancy and delivery so it is important to have someone with whom you can speak freely. See if the gynaecologist is also an obstetrician because only obstetricians are experienced to deliver babies. See that he/she has the experience of taking care of High-risk pregnancy also as you never know when your pregnancy or delivery gets complicated.
If you have other problems like those related to menstrual disturbances or inability to conceive etc. then you need a gynecologist. There is no harm in searching for a person of your choice and visiting her/him once and if you do not feel satisfied you can always look for someone else. And yes, if you seem to have found the right doctor then please do tell your friends also about her/him as it may benefit them also and save them from the search of the best Gynaecologist in Delhi.
