Nursing aversion, early pregnancy symptom?

Ma
My LO just woke up to nurse and I became extremely agitated and uncomfortable while he was nursing. I don't really know how to explain it. I just wanted him off. I couldn't stand the feeling. It made me queasy. I LOVE breastfeeding so this is really odd. I usually fall right back asleep after he latches at night but tonight I was so uncomfortable that I could not go back to sleep. Could this be an early pregnancy sign? I'm about 9 dpo. I suppose only time will tell. Fingers crossed.
