Maybe he's increased your dose too much. You haven't given a reference range for your T4 results so it's hard to know if your T4 is now well below the top of the range (which is 25 in some areas) or if it is still above the reference range (the top of the range at our lab is 14.4)
It could be that you are still slightly hyper or it might just be taking a while for your TSH to come up a bit. It would be worth asking about your periods though. It might be a side-effect of the tablets but it could be something else that your doctor needs to look at.
I'm afraid I don't have much knowledge of hyperthyroidism so I don't know how long it should take for TSH to increase. I'm sure someone more knowledgeable than me will be able to help soon

I have edited your title so that it says you are hyperthyroid which might help attract other hyperthyroid patients that may be able to answer your question
Hi to be honest it takes months to get your levels sorted out when first put on meds. I have been on carbimazole for 22 months. The first thing your endo will do is get your TSH up to around 1 or maybe even higher. Meanwhile your T4 will drop.
My TSH used to be below zero and my T4 was around 30. Now my TSH is around 2 ish and my T4 was around 12.
Everyone on her has the misunderstanding that they will be cured and fast by taking tablets. It is probably because of poor advice from endos ( who talk rubbish) or from assuming that hyperthyroidism will go away over time. neither is the case.
Give yourself time and get regular blood tests and record them to compare. Good luck.
