When both partners have Madhya Nadi, it creates nadi dosha, which Vedic astrology considers serious because it may affect health, mental peace, fertility, and childbearing in marriage. However, solutions and exceptions exist, which means that your Nadi dosha malefic impact will not be there under those conditions.
Check for Nadi Paad vedha. If there is no Nadi paad vedha, it means that Nadi dosha is not there. It is just showing in guna milan but the malefic effect of Nadi dosha will not be there. Checking for Nadi Paad vedha takes a lot of time, which is why most astrologers avoid doing that, and when you approach them for marriage compatibility, they will say no marriage just by seeing Nadi dosha. So, check Nadi Paad Vedha, and if there is no Vedha, be relaxed and go for marriage as all is fine.
