Hello
I have recently found out I am pregnant (5 weeks) I contacted GP and asked for 25mg dose increase so have taken 75 mg for past 5 days blood test Monday 11th result TSh 2.11 and T4 14.2 is this normal GP saying satisfactory.
Further blood tests booked in 4 weeks.
just worried as had pregnancy complications previously
thanks in advance
Congratulations
What were vitamin results at last test
You were getting full thyroid and vitamin testing 2-3 months after increase to 50mcg levothyroxine
What vitamin supplements are you taking
Essential to maintain good vitamin D, folate, B12 and ferritin
Low ferritin, low thyroid levels and miscarriage

hello thanks for your reply
the doctor has failed to complete vitamin tests despite my requesting on numerous occasions and again at most recent appointment I am not sure why they are reluctant to complete this.
I had further testing on 08 April -
1.88 mu/L 10.27 - 4.21
13.1 pmol/L (10.0 - 21.0)
I am taking high dose folic acid 5ml
Vit D
And iron hema plex with vit c, b12, b6 and zinc
Any other advice? I have a telephone consultation with gp Monday and have asked for referral to specialist thyroid doctor but am told this is not necessary
1.88 mu/L 10.27 - 4.21
Is the result TSH?
Range on result incorrect
13.1 pmol/L (10.0 - 21.0)
2nd result presumably Ft4?
Free T4 (fT4) 13.1 pmol/L (10 - 21)
Ft4 only 28.2% through range
Was test early morning and last dose levothyroxine 24 hours before test
sorry
TSH -1.88 mu/L [0.27 - 4.2]
T4- 13.1 pmol/L [10.0 - 21.0]
yes last dose 24 hour earlier test first thing
How long since increasing to 75mcg
Which brand Levo
Make an appointment with GP and request retest at 6-8 weeks…..likely to need further increase in Levo
Get vitamin levels tested yourself if GP won’t
I changed to 75 4 weeks ago when finding out re pregnancy brand was temp tevo but now reverted to levothyroxine
Many people don’t get on with Teva
TSH should always be under 2.5 during pregnancy. Likelihood you will need a dose increase by 4 weeks time, if not now.

Good news about the TSH. FT4 could do with being higher, buy nothing is known for certain. Keep keeping an eye on numbers regularly.
What are the ranges for the above Free T4 result?
I don’t know what this is
Wherever you got this result:
T4 14.2
It should indicate a range - could be something like 9-19 or 12-22
Do you see anything like that?
I did not get a copy. Received over the phone I can request
You want to aim for a T4 solid middle or above in the range.
As noted in other replies, your TSH is a little too high for what we look for while pregnant.
But increasing from 50 to 75 is a great start. 50 was probably too low for the pre-pregnancy time you were on it (although hard to say without more of your history).
I am not a doctor, nor have I been hypo and pregnant, but I encourage you to understand how important at least mid range Free T4 levels are.
If you are indeed 5 weeks, then you are in an excellent time to take control of your bloods, most critical from now through the end of your first trimester when your T4 has a big influence on fetal development.
You should get the range of your blood test asap. It’s either approaching middle range, or it’s still at the bottom. We just don’t know until you find out the range. But it does matter.
This might be an interesting article for you to read as you anticipate increasing your Levo dose over the course of the pregnancy: nejm.org/doi/full/10.1056/N...

13.1 pmol/L (10.0 - 21.0)L

Have you increased your Levo?
I want to reiterate the obvious - that I am not a doctor, and have never been pregnant and hypo. Even though I have spent a lot of time reading primary research and commentary about thyroid levels during pregnancy.
You should do your own research and take all of this in context of what you yourself learn about your individual situation.
I will just say that studies show a higher level of FT4 is needed in the early weeks of pregnancy through mid-gestation - as a lot of fetal development is happening at that time and the baby does not have the ability to create their own thyroid hormones yet. It all comes from the mother’s T4.
They increased 4 weeks ago to 75ml
Sorry results were pasted incorrect
TSH -1.88 mu/L [0.27 - 4.2]
T4- 13.1 pmol/L [10.0 - 21.0]
Your FT4 dropped.
Again - I am not a doctor. But I would seriously review the links others have provided and make sure you are increasing your Levo enough to provide T4 for yourself and the baby together.
Hi
I have not had full vitamin test as Gp said didn’t need it.
I am taking high dose folic acid 500mg daily and vitamin d daily
Is that folic acid prescribed
It’s high dose
Research on Folate and B12 and Neural tube defects and autism
You don’t want too much or too little folate

Yes prescribed folic acid
