Spotting

The first day of my last period was March 27th. It ended on April 1st. My cycles are usually between 43-63 days long. I usually ovulate 2 weeks before the start of my next period. Well, today my nipples are sore, I have moderate cramping, and just wiped and had some pink spots on the toilet paper. My Aunt thinks I may be pregnant (TTC). She said she had what she thought was a period for 5 months during her pregnancy. Any opinions on what this could be? Scant, white CM. This is unusual for me.
