CM question!!

a while back, before TTC I wondered what the stringy egg white type of CM was I got sometimes and learned it was when you were ovulating. I don't recall getting it every month though. this month while TTC I've been tracking it. I took an ovulation test yesterday and it was positive! I was so excited. but there was no CM. not the day before and not today either. if anything it's just damp but not stringy at all. like I said I know I don't get it every month. is that normal? will I still be able to conceive without that CM as long as my opk was pos? thanks guys :)
