Under 3 is preferred when not pregnant, and around 2 is best when pregnant. I think you should try a low dose and then retest 4-6 weeks later and keep re-testing all pregnancy. You are correct, the baby does have a thyroid now so likely your levels will go down with a small amount of medicine and it will be good for the baby.
Yes 3.78 is too high during pregnancy. Ideally they want it at around 2 or below for entire pregnancy. It was .57 to 1.2 during first pregnancy and has been hovering just above 1 for this entire pregnancy. Meds are totally safe to take during pregnancy and are only thing that can help control levels short of losing weight which you shouldnt be doing while pregnant.
I also found out I had low thyroid levels once I got pregnant. I take the lowest level of synthroid and am now sitting at 2.1-2.3 every month. I feel so much better since taking it, it wont hurt your baby to take it, but it could hurt your baby to not take it.
There isn't anything other than medication that will help. Generally with hypothyroidism, you will not have a lot of energy, may have hair loss, extra weight gain.
What's considered normal range for non-pregnant women changes for pregnant women. I'm pretty sure that in the 1st & second trimester, your TSH should be well below 3.78. Best of luck to you.
I would be asking if there's anyway that you can help us naturally without a hormone replacement if there something you can eat or something natural that will help rather than having to take pillow all the time I'm not a doctor I don't know I did have concerns about my thyroid but mine is actually really good considering I'm immediately pregnant following the birth of my son only a few months ago
But does a TSH of 3.78 sound "that bad" that I should be on meds, and it would affect my milk supply. The midwife says it is up to me because according to one chart, anything below a 4.9 is normal. According to a different school of thought, anything above a 3.0 is too high. So I can't decide if I'm okay or not.
I've had hypothyroidism for many years and already had one successful delivery while on meds. #2 due in April and all is well this time too. The meds are fine to take with pregnancy. No worries.
I was actually born without a thyroid, so I've been taking pills my whole life. It only does good for the baby, there are no adverse reactions for your wee one. I'd take what you need while you're pregnant for your own good and for your baby. Also, just fyi, if your levels are too low your milk won't come in the way you hope it will. I never thought I'd have problems nursing, but I sure do. Just do what you feel is best. Your midwife won't lead you in the wrong direction.
