I use Estradot 75mcg - sucks well and is nice and small x
Hmmm lovely sucky Estradot

Re sizes - Estradot is MUCH smaller than Evorel.
Evorel 50 area 4 x 4 cm 16 cm2
Estradot 50 area 2.25 x 2.25 cm (approx) 5 cm2
The one you have been offered is over 5 x 5 cm!
Estradot 75 (the closest) is 7.5 cm2 (2.73 x 2.73 cm)
Also that is quite a big jump - the next dose up for all the other oestrogen patches is 50 mcg and these then go up to 75 mcg. I wouldn't just double the amount immediately without good reason? Maybe there is one? Here they all are:
