Spotting

Marcilyn
For the past two days I've had small amounts of blood in my CM. I'm in my Fertile window right now but took an ovulation test earlier and it was negative. My breasts have been swollen/tender for about a week and my lady parts have been more sensitive than normal. I've been having pinching type pain on my right side, I thought it was ovulation pain. Should I test for pregnancy or wait to see if I miss AF?
