Sore/Sensitive Nipples!!??!

Lauren
Hi ladies,
I have been googling and youtubing and reading glow posts regarding sore/sensitive nipples and I have decided to just write a post of my own to get some of your input!
My nipples are sensitive to the touch, making me cringe every time they're lightly grazed, and my boobs seem the teenyist bit bigger in the past few days. I am currently on my second month of the pill, but my husband and I otherwise have unprotected sex without pullout. 
What do you think the odds are that this is an early sign of pregnancy? 
Also, we're newlyweds and not TTC at this time. 
I appreciate your opinions!! 
Thanks!
