Had some very light bleeding at my cervix last night

Jo • I am a nurse, wife, and mother to one sweet baby girl age 7, and one sweet baby boy age 2, who gained his angel wings on May 18, 2015. We have been trying for #3 since 9/2014. With no luck.
I know I'm in my peak fertile window via my fixed smiley two days ago, but I always do cervix checks every am and pm, last night I had ewcm but, when I actually finally reached my cervix it was so high o had to strain to get it to come down some, and when I checked I had just a few drops of bright red blood on my finger. We use pre seed so where that's been up in there the past three to four days, it's hard to see the ewcm, just can see a hint of white in it. But my concern was the drops of blood on my cervix, could this be ovulation bleeding? Never knew about it until I googled last night, then logged it today, it said mid cycle spotting can be a good sign of that egg popping out of the ovary. Has anyone had this before? I wouldn't have even known had I not checked my cervix, because it was literally a tiny amount at my cervix that hadn't reached my panties or anything, and is gone this morning. Any advice? Or similar experiences anyone? I need reassurance.
