Google not indexing - Pls Help

Google is not indexing my posts. I have tried few times getting them indexed using google console/webmaster tools. Every time use google console the post got indexed immediately but then after few days later got deindexed again. Can you please suggest why this is happening and how to resolve?


Pls note the pages like home page, privacy policy & even contact us pages is indexed but the posts are not indexing. I have 3 posts each 500 words. The site domain is 5 months old and i put all contents more than 1 month already.
