high hemoglobin in second trimester

Serena
So I'm 14 weeks tomorrow and my midwife informed me that my last blood work results showed that my hemoglobin was very high and that we would need to monitor in case of kidney or liver issues,etc. Aside from fatigue and occasional dizziness I've felt great through my pregnancy so far and haven't noticed any issues. I'm wondering if anyone has had experience with this during their pregnancy and what I should expect or be concerned about as I'm a very anxious person
