Stopped breastfeeding

I finally stopped breastfeeding my 16 month old 3 days ago because she bit me so hard and pulled back I knew that she was just using me as a toy or a pacifier and I was completely over breastfeeding especially since I'm 16 weeks pregnant my nipples hurt even more I am hoping I get a good enough break until the baby comes in February and I'm willing to breastfeed her because right now I am completely done breastfeeding I don't want to take the nutrients from my other baby that I gave this baby so much of so I am hoping and praying this break until February is all that I need so I can pick back up and breastfeed my second baby too thank you just needed to vent
