Sore sensitive nipples????

Ha
I've been having sore sensitive nipples, a little cramping (I just finished ovulating 2 days ago) and my period isn't due until 3/11. And I'm super moody. Could these be signs of early pregnancy or do you think my period is arriving? 
So AF came on 2/7 but on my Glow calendar since I didn't ovulate until 2/25... it shows my period isn't going to start until 3/11
What are your thoughts??????
