Breast milk relactation

Right, this is going to sound gross but I can't think of any way better to do this.

So my little one is now 2 months old and I had to stop breastfeeding at 2 weeks old due to his jaundice and poor latch. I beat myself up every day for not being able to feed him and really want to get my supply back so..

I can suck my milk that I have right now out of my breasts myself (spitting it out after)

Would this be an ok thing to do just for a while to see if my milk supply would increase and then try to get my DS back on the breast?

I know that It is a weird and kinda gross suggestion but pumps never really worked for me, mainly because of my bleeding nips!
