Hi, and welcome from another newbie!
In my experience, 7 weeks is maybe still a little bit early to assess whether the patch is providing too much oestrogen. Maybe give it another couple of weeks and see if the pain settles (unless it is unbearable). If you are still in pain then 75mcg may be more what you need.
It is difficult to equate patches and gel doses since we all absorb different types of HRT in different ways. So you might be absorbing better on the patches.
Re testosterone, I wouldn't worry too much about that. It is a 'slow burner' and if you are on 75mcg oestrogen or more then should have enough oestrogen. Took 4 months for me to see any effects from the testosterone (Androfeme in my case).
All part of the 'try it and see' of HRT. It is always scary when you introduce something new with HRT.
