I cannot stop stressing.

So my symptoms are dizziness(slight), dry mouth like I’m always thirsty & peeing frequently but Im also 3 months pregnant. I told my doctor and she checked my blood sugar which she said was normal and the urine was fine too.. she wants me to do the glucose test I think in a month and I’m really stressing because I’m nervous... I feel like a month is too far for me & I can’t take my mind off of this ☹️ I remember When I was pregnant for the second time I had excessive thirst as well.. but the other two I don’t remember.... I’m so nervous for diabetes... 😭 sorry just needed to rant .. idk what to do to calm my nerves
