Last year I suffered a miscarriage and then I was diagnosed with hypothyroidism. My TSH was then at 15. I'm now 5 weeks pregnant and my recent tsh came back at 9.6, this goes up and down and the lowest it has been is 2.7 two months ago. About 30 mins after I eat I feel very sick and could eat again, is there a link between the thyroid function not working correctly and being pregnant? is this a dangerous sign my body is working overtime to cope with the pregnancy?
