Nipple blister? Help!

So I’m not sure if I have a blister on my nipple or what it is! My daughter is 2 months old and I just recently started breastfeeding her (I was exclusively pumping and giving her bottles since birth, super long story) but i finally have been able to get her to nurse from me and it’s been a great 8 days of nursing all day and night! Well now my left nipple (which is my good boob) has 2 clear bubbles at the tip of the nipple and it’s been hurting a lot when she nursed from that boob. I’ve tried several different positions and nothing seems to help. Is this just because I started breastfeeding so my nipples need to get use to it? Or is this something else? I almost don’t want her on that boob at all because of the pain but my supply seems to be just enough for her (hoping it increases now that she’s nursing) but with that being said she needs both boobs in order to get a full meal .. if anyone’s had this before and has any advice for my it would be greatly appreciated!!! TIA 😬♥️
