Stinging/aching nipples?

Whitney

I’ve noticed in the past 24 hours that one nipple in particular but both in some respects are stinging and aching a bit. It feels like they’ve been rugburned or something like it. Is this a typical symptom or should I be concerned about a possible infection or other issue?

Not terrible pain and I just visited my doc over much more important issues, so I thought I’d check in with you ladies first. FTM, 32w4d.
