Boobs hurt when startled?

Ok so this seems pretty weird and I am laughing at myself for writing it, but my curiosity has gotten the best of me. I'm not concerned about it, honestly just curious if anyone else has experienced it.

I'm 7w4d and my boobs have been hurting BAD. But I noticed something odd: when I get startled (for example my husband snuck up behind me and I didn't hear him), I get this sort of jolt of pain in both my boobs, kind of shooting down to my nipples. I assume it has something to do with my body subconsciously trying to protect my baby or something, but I don't know. Has anyone else experienced this, or are my boobs just special? 😂
