hormones. ...

I'm so frustrated right now. last month I had labs drawn and my tsh was double what it should be so I got put on 50mcg of levothyroxine. I have taken it everyday like prescribed but I had my tsh checked yesterday. my tsh doubled. so now it's sitting at an 11.89 when it should be under 3.47. I just finished my first round of clomid and I'm certain it was unsuccessful (never got a positive ovulation test). I'm just feeling so defeated and don't understand why my tsh keeps going up.
