Milk coming out too fast or too much?

My baby is chocking on my milk. I pumped close to 1oz to see if that would help but no luck. I started pumping. Is it because I started pumping ? I started pumping to try to increase my milk supply.

What do I do so milk doesn’t come out so much? My baby doesn’t even want to try latching on anymore. She doesn’t trust it. I have to keep forcing it on her and when she tries she cries.

I press on the nipple and it shoots out a little squirt. 💦💦💦
