36+2. Hand Express?

Hello, i’m 36+2 and a FTM. I had a very small leak from my right nipple this morning. They’ve been sore the past couple of days. Just wondering if it’s too soon to practice hand expressing? (no pump)

I don’t want to collect any, I just want to get the art of it down. But don’t want to do this if it’s risky in any way..

Thanks Ladies.
