Overactive thyroid and pregnant

2 year ago I start to have over active thyroid I was under treatment until 3 month ago. I lost 15 kilo weight and was really sick my doctor advised me to not get pregnant witch was my dream to be a mom i start the treatment I just to use carbimazole 20 mg and after a year changed to 10 mg.

Finally January 2018 my doctor changed to 5 mg everything was finally under the control. I never give up the get pregnant. 2 month ago I found out i’am pregnant my GP told me to stop with my medicine until I see my specialist. Yesterday I found out again my thyroid is again at the higher side witches mean I have high chance of miscarriage. And yes that’s what the doctor told me as well my baby may have growing problems as well. I have to use again now carbimazole 20 mg

The doctor scared with high doses from stopping to 20 mg is quite high yesterday when i left the clinic I cried like a baby on the street it’s hurt a lot when you trying for a long time and finally it’s happened and you get disappointed again. I’am so afraid to lose my baby but i won’t give up on her never. I wish every mom a safe healthy and baby i hope there are some mom’s who can share there same experience and hopefully delivered there health baby
