Breastmilk/ Expression

Aysha
I was having preterm contractions at 32 weeks. The weeks leading up, I was leaking and able to express some milk. When I hospitalized for the contractions the milk or colostrum stopped coming in. Now I am 37 +3 and I'm not producing anything. Did anyone else go through this? I'm a FTM and I'm concerned that I won't be able to breastfeed like I want to.
