I witnessed an egg shaped object flying across the sky.

It was a clear blue sky with some occasional clouds and as i was working outside I noticed what appeared to be an egg shaped object fly across the sky at a moderate speed. It flew on a straight horizontal path. I was confused as i was unable to make out any wings, colors, markings or any discernible features on it, so i pulled out my phone and zoomed in and took several pictures until it disappeared into cloud cover. As an avid sky enjoyer, I am always able to identify aircraft in clear weather conditions. This was an oblong,egg shaped object from what i saw with my eyes and what the pictures show. The object did not correspond with aircrafts in the area listed on the Flight Radar app. It did not wobble or move with the wind such as a balloon would.
