Breastfeeding

Hi, so I’m struggling with trying to create a schedule for pumping to help build a supply for when I go back to work. I’ve looked on Pinterest at different schedules, googles different methods, etc. I tried pumping and got mastitis, and I’m trying to start back up. Because my nipples are struggling and I’m starting to become paranoid she might have thrush. The only thing that I’ve noticed is her tongue appears white after eating.

Today I tried pumping and giving her a bottle, but it seemed she had more around her face then she took in. I just am not sure where to start. Feeling very overwhelmed and not sure what to do at this point. Any suggestions would be great.
