Help with thyroid and ttc. Sooo desperate!!!

Hi!! My name is Alejandra and m very confused!!
I was diagnosed hypo about two years agon and since then ive had two 5 week miscarriages and some other symptoms like being cold..really bad gerd, blurry vision, dizziness etc...
Here is my lab info:
April 2011
Tsh 4.19
Free t3 2.8. Range 2.3 to 3.2
Was put on naturethroud 1 grain and got pregnant at first try a month after...a week later (week 5) miscarried.
Took some labs and free t3 was .94 range .87 to 1.78 different lab. Tsh was .77 and free t4 was 5.10 lab range 6.09 to 12.23
Continued on one grain and never got any better not to mention the sadness from miscarriage.
We waited a year to try again and this time i changed OB, he said since he did not know natural thyroid he wanted me to go on the synthetic one. Only t4...of course i got worse!!
Got pregnant again on February 2012 and i called my new endo...he told me to do some labs to see if i needed an increase...the results:
Free t4 1.10 lab range .56 to1.64. Free t3 3.13 lab range 2.39 to 6.79. Tsh 1.98. Doc told me to increase my dose but it was too late...he never believed me i felt awful because he said my tsh was "normal" Days later i miscarried again!!!
Its been a year and on september last year i decided to switch to naturethroyd again and go back to my holistic practitioner...at least i felt better a little better with him.
I want to try to get pregnant again but im so scared because i think my levels are still off even on two 65mg grains of naturethroyd daily. I still have symptoms.
Here are the last ones:
Free t3 3.1 lab range 2.5 to 3.9 another lab says range is 2.32 to 2.09
Free t4 .82 lab range .61 to 1.12 another lab says range is .79 to 2.35
Tsh .110
He increased my dose about 4 weeks ago from 1.5 grain t,th,s and sunday and 2 grains m,wed,fr to 2 daily. Honestly i did not see much of a difference just than my free t4 increased from .62 to .82 and the free t3 went down from 3.62 to 3.1. At that time i was splitting doses half morning and half afternoon. Swallowing with food (i read dr mercola says that dessicated thyroid has to be taken 10 minutes after breakfast and dinner) and since i did not know i cas taking multivitamins with calcium with breakfast and with the second dose buffered vitamin c. Now i read that the calcium does not get along with thyroid meds so since two weeks ago i started taking the thyroid on empty stomach one hour before food first dose and second one hour before lunch...still my levels dont rise as much!
What do you think is happenning? Do i need an increase? My tsh is already low....also im i taking the thyroid med incorrectly? What levels should i have for a successful pregnancy?? Dont want to miscarry again!!! I just cant seem to keep the baby! Eveything else besides thyroid seems to be right. Im now with a fertility specialist.
Thanks sooo much im so sad now, im 35 and still no child!

Hi! Thanks for answering! I did tested positive for both tpo on the very low side an the other in the middle. Nothing out of range...so i have Hashi?? I havea docs app in an hour...

ThanksH!!K!

After reading your post, one thing comes to my mind...After reading "Wheat Belly", I have learned there is a common link between thyroid problems and miscarriages....wheat. Have you tried going gluten-free? I was diagnosed w/ Hashimoto's last Aug., was feeling AWFUL, actually went to ER one day, read the book, went gluten-free, and feeling great now. Have been on 25 MCG levothyroxine since diagnosed and my numbers remain good.
