I am creating a website for pregnant women, upon registration I am asking for their expected due date. The experience I need is:

• When a user registers they enter their child's due date as one of the fields,
• their homepage then shows a post based on what week of their pregnancy they are in (eg - "You're now 18 weeks pregnant, your baby is the size of an artichoke")
• that post then disappears when a user logs in the next week, and the subsequent post for that week is displayed, (eg - "You're now 19 weeks pregnant...")

I've tried looking at Ultimate Member (/) and the Private Content (/) plugin but that only creates private content for that individual.

I also came across this post: Limit content by user registration date (hoping to leverage the registration date) but as we have 40 weeks of content that code in the Answer is not suitable.

What's the best approach here?
