Having yellowish sticky discharge on my underwear?

I'm on my ovulation week and when I woke up I saw my discharge on my underwear was a yellowish color. I went to touch it to feel the type of discharge it was and it felt sticky. It's thick too. I don't get it because I feel like I'm supposed to have the egg white discharge but I'm not. I recently got treated for a yeast infection so I don't think it can come back so soon :/. And I don't have any stds. I haven't had sex since my last period which was about 2 weeks ago. I have gotten this type of discharge a couple of times but I don't remember if it was during my fertile week since I'm new to this <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> and I just started keeping track. What should I do? Should I drink more water? I only drink about a bottle a day. It doesn't have a smell or itch btw.
