Breastmilk!

Help! My baby is 6 weeks old. I was doing really well with pumping, only 4 oz each side but it was better than nothing! We had to go on an emergency trip to My husbands family’s house and watch their kids, I stupidly forgot my pump and it was a 6 hour trip from home! Well sadly my baby doesn’t latch on and it was frustrating! I couldn’t pump for two whole days but I tried doing some hand massages. Long story short I came home and pumped right away, I only got 1oz! All together! Then it went down to nothing and I tried everything! Power pumping! I always pump every 2-3 hours! I tried lactation cookies, drinks, teas, body armor drinks! Please help me I don’t know what to do!!!
