first time pumping. please read!

Ashley • I crushed PCOS!!!! After almost 4 years of TTC my prayers have been answered. End of Sept baby!!!
My son was napping and I decided to bust out my pump and try. I sat here for about 15 mins ( attempted both sides) and this is all I got. About 0.8 ounce. I don't know if this is good or bad. I'm not giving up but I'm very nervous. Please advise/ encourage me. 😩
