First of all, OMG I love your puppy's name! Fiona Apple is like my 90s icon!
To answer your question, if she is in fact preggos, if its early in the PG not a big deal to spay her. Otherwise, if she's not PG, 8-10 months is the ideal time to get a dog spayed. No worries. Just ask your vet what they think is best. Keep us posted.
