I can't really get a scale of the picture to know how big that white stuff is.. eggs are usually easy to tell.. I am worried it may be a fungus of some type, but without a clearer picture I really can't say. I would wait for someone with a better answer for you.. worst case take out the cheato and use some scissors to cut it out.
yea im not waiting around for someone to tell me its a fungus lol, i just got rid of it but i cut it open first and it smelled badddddd when i did. didnt look like anything.. it was about the size of a quarter. my phone is beyond shot and wont get a new one until mid april so pics are pretty bad until then
