Lut, I'm pretty sure the vet will not want to spay her while she is in heat, anyway. I think there is a lot more risk, then. I will also add that I had Mimi spayed while she was in heat and Shrimp Boat too! I have never heard such wailing and howling in my life!!!! And the things Shrimp Boat would do to get close to my husband! OMG!!!! LOL!!!!! She would back up into his face at every chance!!!!! Tell your hubby to watch out!!!!! You have my sympathy!!!
