Ovulation?

Hi guys!

I have an ovulation question. I am currently veryyyyyyyy late for my period (24 days) negative pregnancy test I know I am late due to under eating / weight loss which I am working on to fix.

On Thursday / Friday last week I started to notice the slippery clear discharge. Then a couple days later on Sunday I noticed (TMI) a big string of clear watery slippery discharge coming out of my vagina. The day after I noticed the same and ever since I have been having a lot of clear discharge like a lot.

I think we all get used to period tracking apps, so I am assuming this discharge is a sign of ovulation as I have always known to expect that type of discharge on ovulation. Today I have also had discomfort feeling in my ovaries area.

Can someone please give me your opinion if this is definitely ovulation and how long to my period comes? Its so hard to track without an app when I have gotten used to looking at an app for years!!!!

Thanks guys!
