Is my milk drying up?? 😢

Hello I’m a FTM and my baby is 6 weeks old and has started moving his head side to side while I’m breastfeeding. It’s usually about 5 minutes into feeding, he is latched very well, and starts pulling my nipple and turning his head side to side. Does this mean that I’m not producing enough milk? I am going through a cold this week and haven’t recovered yet and I’ve been reading online that it can slow milk production.
