Discharge clarification plssss


Okay so I’m new to the whole identifying your discharge and what it means in regards to your ovulation. So when you’re fertile your discharge is clear? like egg whites? and it’s stretchy? Because my ovulation window (according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> ended on Saturday June 20th) but I just had some self care down there gave myself a good clean and I noticed my discharge was white but really stretchy so does that mean I’m fertile or is that normal? My period is expected to start somewhere around the first few days of July. So is <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>’s ovulation window for your cycle accurate or is it more like an estimate?
