Crazy Right Vibrating Titty Explosion

Ally • Practice makes perfect.
So, two nights ago, around 11 PM, just as I was falling asleep, I was startled wide awake by the feeling of spontaneous vibrating in my tit. ONLY the right tit, mind you. Terrified, I called my mom who said she never experienced anything like it. 
Next morning, I swore it had grown and was now a good 15% bigger than the left one. I asked my husband to confirm - poor fella - and he agreed it had grown overnight. 
This happen to anyone else?
Pregnancy is so weird!!
