Jelly like substance in milk????

Sarah

I've been exclusively pumping since baby was born 9 days ago. I have been pumping more milk but have noticed jelly like blobs in the bottle. Is this safe to feed the baby??? My nipples got blisters due to using a flange that was too big and I'm dealing with really sore nipples...wondering if this has somethimg to do with it. Praying that this gets easier😪
