Spotting?

Kasey
I am ttc #1. We have stuck to the Glow calender this month. I know I ovulated because I get pain in my overies for about a day or so. I have been feeling sick since friday. Someone said it may be an UTI, so today I bought the test to test at home and it was negative. I also took a pregnancy test which is also negative. I ovulated around July 19 so I think that puts me 7dpo. I have had crampy/pain in my overies and uterus off and on since saturday. I went to the bathroom this evening and there was light pinkish/reddish blood. It looked like cm as well. After a couple wipes it was gone. I went to the bathroom a bit later and nothing. About an hour I went and there was a very small faint amount with one wipe. Af is not due til Sunday and I have never spotted except on af day or if I was late. Would this be normal for implantation? What was your implantation spotting like?
