Ever since about 4 hours after the trigger shot, my boobs have been killing me. That's how I knew the HCG was in my bloodstream, because I got up from the sofa and immediately flung a protective arm across my chest.
This is not your average "I'm about to get my period" hurting, this is no shit "if I don't strap these down in a jogbra they may break off" hurting. And it's not getting better at all... And may be getting worse. Case in point, I am wearing my pajamas and my jogbra. To bed. Again. I would wear the bra in the shower if I could.
I wish I could say "ooh look, an early symptom that this worked" but since it's been going on since before ET, even at my most delusional I don't think that I would buy that logic.
