Milk drying up!

HELP!! I think my milk may be drying up and I am so upset! I have been doing great pumping. My LO is 7 weeks old and has not breast fed since he was about a week old due to nipple confusion. He was born tiny and we had to give him supplement bottles. I normally get close to a full 5 oz every time I pump, but the last 2 days i have only pumped out 2 oz all together! I am taking Fenugreek and Lacation Plus vitamins and they seem to have been working this whole time until now. If anyone has any suggestions please let me know, i am willing to try anything. I just want my baby to have my milk 😢
