Our take
When your fertility doctor recommends it and the TTC community backs it up, that's about as strong a consensus as you'll find for ovulation testing.
Most MBTI tests just spit out a four-letter type — the Michael Caloz test actually shows you the cognitive function breakdown, which is what serious typology fans want.
