Does anyone have an understanding of blood levels? So my thyroid level was 2.1 last month, now its 4.6 , progesterone greater than 40 and estrogen is 88.....I had the <a href="">IUI</a> last week, I have to now take estrogen med to boost number up.....with the increase in thyroid, does that mean pregnancy is taking place?? I'm so confused, that's a big jump in numbers
