How soon in pregnancy do a woman's nipples become more sensitive? - flukes more condition_symptoms

My girlfriend and I are safe, but we think they have been pregnant in the last 2 weeks. I realized tonight, while teasing, she reacted quite differently. My nipples seemed to enjoy the game more than usual. Is this a coincidence, or can also be an early sign of pregnancy?
