Colostrum collecting

I’m 36 weeks and have started collecting colostrum. I have taken advice on this and I am ok to do so. Anyway.. I haven’t been able to do it 4 times a day as I’ve felt a bit sore. So have done it once a day for now. I’ve gotten around 0.3ml each time (from both boobs) is this Normal seen as I’ve only been doing it once a day and only just started? Anyone got any tips?

If your just going to be negatively opinionated please don’t bother commenting. Don’t need no Karen’s on here thanks 🙃🖕🏽
