My first question is when you have launched your website. If it 2-3 days back then give it some time Google takes time to index new sites and make sure that your sitemap is uploaded and working properly (if not upload sitemap.xml). Also, you can request Google crawl and fetch your site. for this can help you Ask Google to re-crawl your URLs.
Some other reasons could be:
- Check for Crawl Errors.
- You may have lots of duplicate content
- The site may have NOINDEX in the meta tag
- As you have a WordPress site, you may have accidentally kept the privacy settings on. Go to Admin → Settings → Privacy to check.
If you want proper guidance on how to fix these crawler issues, you can refer to this article - Why Your Site Is Not Indexed By Google
Hope this will help.
