is it too late to build up my supply?

So I'm 10 weeks pp, exclusively breastfeeding and pumping occasionally. Last week I exclusively pumped and was getting enough for a feed and a half or sometimes 2 feeds. Anyways my mum came to visit this week and so these past couple days iv been really lazy with feedings and pumpings, my mum would take the extra milk I pumped last week to feed my baby so I could rest, essentially my daughter bottle feeds and instead of pumping I would take the extra time sleeping. I wake up with hard and sore breasts and when I eventually pump I get quite a hit. I'm really mad at myself that I did this cuz I knew it could have a aging effect on my supply (although so far so good) I just don't want to ruin my supply for the future as I plan to breastfeed until a year old. What should I do now? I'm back to nursing her exclusively. Sometimes she also sleeps a lot longer especially during the night and I don't want to pump and empty my breasts for her o wake 30mins-hour later and not have enough to feed her! Any suggestions and advice would be helpful? I have a hard time getting into a pumping schedule cuz o feel as tho if I pump after a feeding there isn't enough milk to fill my baby up for the next feeding!
