8weeks pregnant

I've been wondering is it normal or its a hormones changes during pregnacy to have high blood and diabetes..??coz as i know i dont have any history of that...so been to the dctr and doing chck up they said my BP is high...so they ask me to track down my own home tracker at home...so far its normal...and recently they take blood test and say my sugar level is slightly high...??...??is it becoz of our hormones changes..??
