Feeling stressed..

Just gave birth to my beautiful baby boy on Wednesday. I wanted to breastfeed like I did my oldest two children which are 10 and 13 years old. I breastfed them maybe 8 months max.. I'm becoming frustrated. I mean I know you only make the colostrum the first time around but I feel like I'm shooting out dust..Like is there anything in my breast? I slowly feel them getting engorged but I be feeling like my ducts are blocked..I say the first day I breastfed him was very good! I bought all the lactation products and I also have a pump when my actual milk comes in..I don't know what to do! I don't want my baby to be hungry I just feel like nothing is coming out or maybe my nipples are blocked or just something. I also have a nipple device..Any ladies have any advice that can help?🙏🦋🦄🧡
