The first month long trip in Feb might have also triggered the discussion as officer might have assumed you were looking at another month long visit this Feb.
Personally another visit in May seems too quick to me. I would wait until the summer UNLESS May is when you have the time.
Also, not knowing about your type of employment/ your situation you might want to consider delaying a trip so soon.
If you’re a student. I would delay OR if you are someone who works from home and doesn’t have to go into the office I would delay the trip.
If you’re in a more established career with a home you own, I would visit.
Either way, expect a visit to secondary on your next trip and feel good/ lucky if it doesn’t happen.
