After two miscarriages and a year+ of trying to conceive I saw an RE. After some initial bloodwork, it was discovered that my TSH was borderline for hypothyroidism. It was around 3. I went ahead and started 2 fertility cycles with no success. Then after a follow up blood test I was finally diagnosed with Hypothyroidism, my TSH went to 7. I started taking Synthroid about 5 weeks ago and took a break from fertility treatments in order to concentrate on getting my TSH levels stabalized. During that break, we got pregnant naturally, but I ended up miscarrying. My TSH levels were around 3 at time of miscarriage. My medical endo has increased my Synthroid and I am hopeful this is all I need to get my TSH level stabalized enough to get pregnant and sustain that pregnacy. Its amazing how one hormone out of whack can cause such havoc. I have learned through this experience how important thyroid health is and plays in fertitlity. Stay on your medicine as it does play a vital role in pregnancy.

OP, my experience is that if you're hypo weight loss is just not that easy, but it was very hard for me when I was not medicated--mostly because I was so damn tired and because I could barely build muscle, etc. Have been on thyroid meds for nearly 15 years and after the first 2 or 3, I have maintained a normal, healthy weight, even after having a child. I can't eat whatever I want--am quite conscious without being punitive-- and I do exercise as much as I can, and I will never be skinny, but I finally found a good normal range which allows me to eat like a normal (if healthy, weight conscious) person and maintain a normal, healthy BMI (around 21).

OP here. Why is weight loss harder on the medication? I thought it would be hard if you were not medicated?

I just had a miscarriage this past week. I went back to my initial pregnancy panel blood results and my TSH was 3.2 - the normal range went up to 4 or so on the blood test results I received from my doctor. I had a physical in July and my TSH was 2. When I reviewed the pregnancy panel blood test results at 5 weeks - my NP told me my progesterone was low but everything else was normal. I began taking progesterone suppositories at 5 weeks and the progesterone level increased from 8 to 23. At 9 weeks I found out I miscarried at 8 weeks. I am thinking now that the office missed that my TSH was too high for pregnancy even though it's normal for other purposes at 3.2. What do you all think? Is this a huge miss on the part of my doctor's office for not picking up on this early in my pregnancy?


I didn't realize taht 3.2 TSH level could cause a m/c. That is really scary, since to me, that is borderline. Do you know why it fluxed so much from July's 2.0 reading to 3.2 ? Are fluxes like that normal in thyroid? I too am so sorry for your loss.

thyroid disease can cause weight gain or loss. Hypo usually causes gain.

Once you are on the meds, it makes it harder to drop weight. It can be done - but you have to focus on your diet and exercise. I know that sounds like typical weight loss advice, but it is even harder than your normal "I want to drop a little weight" It took me 6 months to drop 15 lbs. There is conflicting advice on what you can and cannot eat, but I cut way back on carbs, counted my calories, and ate a lot of proteins.

I need to get back on it, though - I have let my diet and exercise go this summer due to the stress of house hunting, moving and now living in a house under construction. It sucks that you can't just drop 10 lbs in a month, but it just isn't that easy when you're battling the thyroid.

Good luck.
