Jogi80, I can definitely understand your reluctance to take a drug, as I feel exactly the same. Thyroid replacement is not a drug in the traditional sense, though, as it is straightforwardly a replacement for something your body should be making but isn't. I'm not sure if anyone has explained a few contextual things about your situation:
1) 114 / 144 are extremely extremely high TSH results. The 'range' doctors will often stick to goes up to 10, but actually most healthy people have levels of below 2, and many people are very ill with TSHs only a little above that, like 3 or 5.
2) It's very unusual to be in your position of having a high TSH, particularly such a very high one, with no symptoms. This suggests something more complicated is going on. The TSH is actually a pituitary hormone, and it is only indirectly a marker of how much thyroxine your body is producing. Probably something is out of whack somewhere in this hormone regulation system. This is something you'd want to know about, as other hormones would likely be effected. Most people on this forum have Hashimotos, which is an autoimmune disease that attacks the thyroid and produced antibodies that can be tested for, and is really the only straightforward way to become hypothyroid. It would be good to find out if you have antibodies ASAP, as if you do you'll have your solution to at least the cause. I've had my thyroid removed, and get numbers in the 100+ range with no medication. So if this number is an accurate representation of your thyroid function it means you've got almost none left. Which could be a good thing, as the process of losing it is probably worse than having none!
3) If you weren't pregnant, I think I would advise you to stay off the Levothyroxine if you don't feel you need it. All these blood tests are very fallible. In my journey to get better I've recently had a TSH of 100+ and felt tons better then I did with a normal TSH, so I know first hand that these numbers do not accurately reflect well-being or health.
The reason everyone in this thread is so insistent you must medicate and drop that TSH is because hypothyroid pregnancies are very vulnerable. It's dangerous to be pregnant with a high TSH, and many people have miscarriages, often repeated ones. It's bad timing to be at this point in your illness and get pregnant, because you have no clue why your TSH is so abnormal. But the picture is further confused by the fact you managed to get pregnant at all, which shouldn't be possible if your TSH is that high for straightforward reasons. So clearly your body is healthier than would be expected with a TSH like that.
4) Speaking personally. I think you've come head to head with the most distressing emotional element of being hypo straight away. My situation has some similarities to this, in that after my thyroid cancer my blood numbers have not really made much sense, I've failed to improve and thrive and no one has really got a clue why. I became ill in my early 30s and am now 37, and I do wonder if this means I've missed my chance to have a baby, or if I will recover my health in time for it to be viable, or take the risk of having repeated miscarriages or doctors meddling with my hormones and messing up my and my baby's chances. I may just round the situation up to 'infertility', and be too scared to ever take a roll of that dice. Doctors know so little about how to manage the pregnancy, and its common for people to turn up in the forum and describe miscarriages where its clear the doctor bundled the whole thing and was completely at fault for the loss of that baby - it's heartbreaking.
But your situation is so unusual and confusing it's not clear you are literally, straightforwardly hypothyroid, so there's always a chance things will be fine, but there's also a chance you are in this very high risk group for miscarriages. Probably no one will accurately be able to tell you which, and you can expect doctors., even specialists, to be very unfamiliar with what to do, and therefore to put you clearly into one sort of box and give you very generic treatment.
