I count to about thirty before it eases off
Reading this at the right time, I hope. Let me give you the straight answer first: no, feeding is not meant to be painful the whole way through, and toe-curling pain at nine days almost always means something specific and fixable, not that you aren't tough enough. That "it toughens up" line is one of the most persistent myths on this board and it keeps parents suffering longer than they need to.
Here is roughly where the line sits. In the first 10 to 14 days a brief tenderness as the baby draws the breast in, a stretch of maybe 30 to 60 seconds of discomfort at the start of a feed, fading over the first couple of weeks, is common and settles. What is NOT in the normal range: pain that lasts the entire feed, a nipple that comes out flattened, ridged, or lipstick-shaped, or cracking and bleeding. Those point to a shallow latch far more often than anything else, and the piece on why breastfeeding hurts walks through how to read the difference.
The usual culprits, in rough order: a shallow latch, which is the big one and often fixes with a deeper, more asymmetric latch (chin buried, baby's nose free, a big mouthful rather than just the tip). Then tongue tie, anterior or the sneakier posterior kind, which can stop a baby dropping the tongue and keep the latch shallow no matter how good your positioning is. Then thrush, a Candida overgrowth that tends to arrive later than day nine with that burning, both-sides pain jessb92 described. And more rarely vasospasm or Raynaud's, where the nipple blanches white after a feed and then throbs, worse in the cold. Different problems, different fixes, which is exactly why a name from a forum only gets you so far.
Timing to hold onto: once the actual cause is addressed, most latch pain eases within a few days, and a cracked nipple usually heals in about 3 to 7 days once it isn't being re-injured every feed. If you have worked on the latch and it still hurts after roughly two weeks, that is the signal to get hands-on help rather than wait it out. The order I'd suggest is get someone to watch a full feed in person, a midwife, health professional, or a board-certified lactation consultant, because twenty minutes of watching tells them more than any thread can, and the notes on getting a good latch are worth reading before that appointment so you know what they are adjusting. For the thrush or vasospasm possibilities, that's a conversation with your own GP, since those can need treatment I can't sensibly guess at from here.
