this means you have a normal FSH for day 3, under 6 is excellent, you have a normal TSH, which means your thyroid is fine and you have a normal LH, if the LH was higher than your FSH you could have had PCOS.
I went through IVF because everything "looked fine", just not pregnant and they found out that my husbands sperm couldn't penetrate my egg. I'm still in my 2ww.
