Should I be concerned ??

Kayla • Had a miscarriage in April of 2020 at 12 weeks 😔 Baby Grayson due November 2022 💙🌈

I went for hormone testing and ultrasound everything was good but this confused me ... i also got a ultrasound and everything looks good normal uterus, normal overies with no cyst.. should I be concerned by this ?? What’s the difference between testosterone and testosterone free ??? Help ! Also side note my doctor told me she’s not too worried about it but won’t answer my question about what’s the difference
