Spotting while fertile

Earlier today I felt something coming out of my lady parts so I sat down on the toilet and wiped. I realized it was just my cervical mucus because I'm fertile right now so I thought oh okay no big deal. I wiped again just to be clean down there and I noticed a little bit of blood. There was a little more blood after taking this picture but not much. I've never had this happen and just wanted to know if it was normal!
