ttc and high thyroid..

I went for a full hormone profile and everything was fine except for my thyroid was a little on the high side. Anyone have this and has it hindered your ttc efforts? I'm starting meds on Thursday and was wondering if anyone can give me some advice on this issue.. thanks ladies. I also have an issue with progesterone. I went for my cd 22 blood work and progesterone was only 4.2 .. Im so heartbroken and I feel all my ttc efforts are just pointless..
