What is a normal thyroid (TSH) level ?

Hi guys,

I was tested back in Dec for thyroid and Dr told me it was normal. She might have told me what it was but i can't remember for the life of me what it was.

I got tested recently for some blood work as I have RA and my Dr wanted to make sure that everything is good. She told me my thyroid is 3.3

Is that high? Do I need to bring it up to my Obgyn? I had a mc last month at 5 weeks and I don't want to deal with that again if it's because of this.
