Hi,

I was just wondering if anyone with hypothyroid has gotten a false negative on a HPT? And is so, how long before you got a positive result?

Samantha,

I apologize for my ignorance, but what test are you referring to when you say HPT?

Oh, I'm sorry, an HPT is a home pregnancy test.

Now I get it....

Sorry its been a long time since I've had to do one of those, 6 years anyway.

But I have a friend whos HPT never came up positive in the beginning (and she

has 3 pregnacies). I know that she is hypo now, wasn't diagnosed as being hypo

then, but I supposed she still may have been. Especially since she wasn't diagnosed

as being hypo until after she they found out she had thyroid cancer. But that's

a whole other story.

At any rate, I suppose there could be a connection. If I were you and really wanted

to be sure, call the Doc and get a blood test. If you don't have ins. or don't want

to go to your family Dr, I'm sure there is someplace you could go to get the test done.

Actually, Samantha, it is interesting that you should bring this up. I am hypo (had a near total thyroidectomy about 6 months ago) and have always had irregular cycles--more irregular as they have been adjusting my Levoxyl dosage. This cycle (57 days) has beaten my longest one ever by 9 days. Once I got past CD 48, I decided I would test just in case, because I am off birth control and I could be pregnant, but it was negative. A few days later, still not period and I tested again...still negative.

It could be that I am annovulatory because my Levoxyl dosage is still in flux, so I have an appointment scheduled with my OB GYN to figure out what is going on. I doubt I am pregnant, but there was a little glimmer of hope there--I am 35 and would really like to finally be pregnant.

Please post if you learn anything...

i am so glad somebody else has asked the same question that i have been asking! ok i am hypo and been pregnant 8 times (3 healthy , 4 miscarriages and prego now) i asked this on another message board(pregnancy) i was wondering if being hypo can cause you hcg levels(pregnancy hormone) to be low in the beginning of pregnancy? a friend and i are due at the same time and we both took a pregnancy test at the same time and hers was positive mine negitive so i kept testing for the first 6 weeks where i got a faint positive(6 weeks later). Now this has happened to me all 8 times i have been pregnant so i was wondering if being hypo has something to do with all my false negitive hpt results. And i am also wondering if being hypo has caused my 4 miscarriages (i was'nt on any meds at the time) because i have read being hypo can cause a higher rate in miscarriages. well i just thought i should share my info. good luck to your reasearch, ~tanya.
