Hypothryoidism and pregnancy

Claire
I am 5 weeks pregnant and was diagnosed with hypothryoidism 3 years ago. I've always struggled with fatigue even though I have been on Levothyroxine. I've found the past few days I am really struggling to get out of bed in the morning. Has anyone else had these issues? Also, I met with an endocrinologist a couple years ago who informed me that the moment I got a positive pregnancy test I needed to increase my thyroxine by 25micrograms. My GP wasn't much help in this matter but I increased them . I'm just hoping I can find someone going through the same situation who can offer some guidance/reassurance x
