It might be worth trying half a pump and building up slowly to see if it makes a difference. 
The advice I was given by a Specialist Clinic was to be consistent with a dose to allow it to work effectively and allow symptoms to settle. 
Sore breasts can also arise from low oestrogen, according the reading I've just done. 
If the size has also increased I guess it could be related to higher oestrogen levels. 
it's so hard trying to find a balance
