I am pre diabetic with type 2 diabetes and have thyroid too I am 7 week pregnant,

When I missed my periods I checked with doc and found out I am pregnant . Doctor gave me weird look by saying you are type 2 diabetic how can u get pregnant, and its risky for a baby, and delivery of a healthy baby, fetus Heart rate is coming 115 which should be nearly 140 beats,

Now I am controlling my diet and taking insulin 4 times a day with other tablets, and walking for almost 45 mins evryday. But still in glycometer my dibates counts are coming littile high. I am really worried, will I deliver a normal baby, these things are stoping to be happy. M getting a unwanted thoughts of abortion too. Is there any mother here who were prediabetic but delivered a normal baby after so many complications? Please help, I am not able to sleep because of tension.
