Newly pregnant when to see dr


After trying for a baby since another miscarriage last August, I am so, so happy to have had a positive pregnancy test :)

I had an inkling I may be pregnant so got my thyroid bloods tested on Wednesday, results will be ready tomorrow. I take 50 mcg levothyroxine daily after testing positive for antibodies and tsh rising above 2 whilst ttc.

I was thinking of ringing dr on Monday to get an appointment with my usual GP who put me on the levothyroxine last year, for continuity reasons, earliest appointment would be Wednesday next week. Would that be ok do you think or should I book in for tomorrow when results are in?

Just wondering what would be best, especially if I need a dosage increase. I'm only about 4 weeks now.

Levothyroxine dose is usually increased by 25-50mcg when pregnancy is confirmed to ensure good foetal development. Perhaps you could take an extra 25mcg daily until you can see your GP on Wednesday.

Thank you I'm so excited!

So I can just take one and a half tablets?

Sounds like a plan as my usual GP was great so think I'd be happier to see her, unless my results are way off then I'd probably best see someone asap.



Yes, 1.5 tablets for now. Post your results and ranges in a new question for advice tomorrow.


Will do x
