This is all about discharge

So I'm wantin to get pregnant, and had a period about 2 weeks ago. 3 days ago I started have weird discharge, my underwear would he completely soaked after a few hours. Thin and slimy. Thought I may be ovulation so I had sex last night. Bit I'm not sure ovulation is like a water park in your pants? 
Can some one tell they've had this before a what it is? 
Also, we've been trying to get pregnant for several months now
