6 weeks postpartum/breastfeeding/spotting

I’m a little over 6 weeks postpartum and have been trying to breastfeed consistently. I haven’t been very good at pumping...mostly because I feel tied down to the couch for a half hour and I’m not able to take care of other things. I stopped bleeding from the birth around 5 weeks. I do supplement with formula when my husband needs to feed him or my nipples are too sore or I hadn’t pumped enough. Yesterday and today I had a bit of spotting. Is this normal or could that combo be decreasing my supply and tricking my body into menustrating again? When I saw the blood I felt so sad because I hadn’t been doing what I needed to to keep my supply up or something. I’m scared I’m not providing for my little guy and that I won’t be able to breastfeed him anymore. I honestly love the bonding time and plan to do it until he doesn’t want to. It’s my first baby so I have no idea what to expect. Pls help 😢
