Is my baby getting enough?

Roxy
Last night from 11:30 pm to 3am my baby wanted nothing but the boob and would get so pissed in between feedings when I had to burp her. She is going to be 7 weeks, and today she was like that around 4pm to 6 pm. Im worried she's not getting enough, am I producing enough milk for her??? She would even take the boob and then wine a little on the boob like she wasn't getting enough and she would fall asleep on the boob and then after I burped her " if she would stopped screaming enough for me to" she would want more. Am I making enough for her????? I'm feel so sad sometimes like she's going to starve, and I'll even squeeze my nope and it will squirt milk.
