TMI Question

For anyone who has been pregnant and had the symptom of sensitive/sore nipples, what did it feel like? My nipples have been getting progressively more sore, it feels like I got them pierced (I’ve had them done so I know this pain😂), but more so my left one. They burn when I’m not touching them and then if I hit them or lean on my desk I get a sense of them being sore.
