No not yet...my ob gyn says he dont think I should have any problems in fertily knowing I have a child already...But I do worry about the patch BC i was on...have you heard any bad news about them?
I have heard that it is true you dont want your husbands testicles to get too warm, because it can reduce sperm count. I dont know how much of that is an old wives tale, but my philosophy is always "better safe than sorry," and it is worth it to give it a try. Although I serisouly doubt that is causing a real problem, maybe ask him to switch to cotton. Then, either way, it wont be nagging on you, leaving you wondering if that is the issue.
I see that you have had yur thyroid checked, have you had other ferility testing? Have you had any other blood work or maybe an HSG?
