Though... maybe you could add a male (keep them seperated for a while, put the male in a large bag and float it to make sure they'll get along) maybe something magical/unlikely will happen.

I would first research web sites before you have a go at breeding.
Yes they are probably eggs.
Just google for : breeding bettas , and you'll come up with allot of info!
OR use the search function on this site! I'm sure you'll find plenty of info, as this has been discussed allot of times already!
