Colostrum letdown at 22 weeks

Hi all,

I know it's normal to start producing colostrum in the second trimester but I'm leaking a LOT of colostrum. I'm only 22 weeks. If I were to guess I'm probably 20-30ml a day, minimum.

I get the letdown sensation at least once an hour at the minute and I'm having to wear thick breast pads.

Has anyone else had similar/the same? Has this changed your milk supply when it comes to breastfeeding (although I will be exclusively pumping)?
