 Show Car98fof 28/06/2010 at 8:55 pm Was looking up stuff online about pregnancy with an underactive thyroid and found loads of stuff about people getting loads of false negatives due to having an under active thyroid...My period is late and my OH and I have been ttc, I feel very pregnant but all my tests have been negative. Do you think its possible that my under active thyroid could be causing false negative pregnancy test results? Have any of you had this problem? Chr04crz 29/06/2010 at 7:42 am Id also be interested in the answer to this. I also have an underactive thyroid but apparently levels are stable on the Thyroxine levels im on. I had no problems with getting BFP with DD but it would be good to know for the hopefully next BFP jea31yxl 01/07/2010 at 12:11 pm Hi Cara How have you been since posting? My limited understanding is that an underactive thyroid gland can affect certain hormones in your body, which may give a negative result. It may be worth you asking your GP to do a blood test to check your hormone and thyroid levels. jeanettex Similar threads jea31yxl 01/07/2010 at 12:15 pm Id also be interested in the answer to this.

I too have under active thyroid and for my last baby who is three and a half i had three negatives before getting the positive but I wasnt diagnosed as having under active thyroid at that time. But it is a possibility that you are pregnant. Rac47skc 02/07/2010 at 1:14 pm I have an underactive thyroid also. At the moment I am a week late and have all the signs but tests are negative. I saw dr yesterday and the first thing he said is to check my thyroid levels as this can have an effect so it does make a difference. Dkm07jan 22/06/2016 at 8:08 pm I'm in same boat... any update?
