Sign of ovulation???

Hi ladies!! 
I have a question about ovulation.  I'm on 3 months of ttc and I'm confused about one thing. Every month around mid cycle (since off bc) a big glob of thick sticky glue-jelly like cm comes out(sorry tmi).  It's only one time and about a day later I'll get ovulation cramps.  My question is if anyone else gets this? And if so, is that a good sign of ovulation?  I've tried researching it, but I haven't been able to find any solid evidence as to what it is. 
Thank you!!!
