I'm an endocrinologist, so the sort of specialist you are going to see on Wednesday.

Ideally it is best to wait until the thyroid is controlled before getting pregnant, but I have seen plenty of successful pregnancies in people with overactive thyroids.

Your tablet (guessing you are on carbimazole) is not the "wrong" medication, but you will probably be changed to something better (propylthiouracil) as there are theoretical risks with carbimazole.

Congratulations on your pregnancy! Do try to enjoy it. smile

I also have an over-active thyroid. I had a blood test in January that picked up slightly high T4's, was referred to a specialist. We had been trying for 15 months with no success and had gone to the docs for a check up. We had an appointment to see specialist on 15th April. Who advised us to stop trying until problem under control. 3 days later had a positive pregnancy test the first specialiset recommended an abortion when we told him, as there is no chance a pregnancy would be successful! Got a second opinion and they were so much better and less scary and intimidating. Was put on PTU immediately, one a day until my levels were down. I'm now 25 weeks and my levels have been in the normal range since I was 16 weeks, I am still taking PTU [polythoura-whatsit], they aren't sure if it's the pregnancy or medication so I will be watched before and after labour to see for changes in me and LO. Was advised LO maybe small, but measurements are average at the moment. I see the specialist's regularly [every 4/6 weeks], have blood tests to check levels, and they've kept me informed and have made sure that I understand what's going on. I've certainly been much happier asking for a second opinion, and feel that I'm now chilled out and enjoying it now.

This is my first post, although these threads were a lifeline for me when i miscarried in february - thank you ladies. I am now 5 weeks pregnant and have an over-active thyroid. I have not yet received an appointment with an endocrinologist, but was put on PTU and told to avoid getting pregnant whilst taking it. Although we were not being particularly careful, I wasn't expecting to get pregnant so quickly following the miscarriage. I am now trying to relax but am very anxious about the possibility of another miscarriage, and the possibility of PTU increasing my chances of m/c.

Lizzy, just wanted to say that I had the same worries through my pregnancy with DD they were forever changing the dose of the PTU and was worried what affect this would have on my unborn child. I went to the big hospital for joint antenatal/endocrinology care, appt every 6 weeks, Bloods taken and symptoms checked. Also was classed as high risk delivery, so plans of having a water birth or MLU was out the window. Scans picked up small baby at 32 weeks so regular scans after that, predicted 6lbs, DD arrived 5lb 13oz. My thyroid seems to be settling down, though BT every 3 months to check levels.

It was only picked up my levels were a little high when I went to GP as was 12 months ttc, was PG by the time my endocrinology appt came through.
