Suppress means to slow it down so you would be tired, etc.... Birth control does that to our thyroid according my books on the subject written by MD's. Wish I knew the why's, but I don't take birth control, so never needed to pursue it. You can usually do a search on the net and find answers. Use the keywords, "thyroid , birth control, side affects, or is it effects?"
Your TSH should be around 1.0 That's ideal for a female.
