Yes, sounds like sex-hormones kicking-in (it is the season, trust me I know), and I agree with Itzjbean, the best thing you can do is to just let her alone and don't try to push her to do anything she doesn't want to do, because that's when you're going to get bitten and see the aggressiveness...And certainly don't "force" her to do anything she doesn't want to do, unless as Itzjbean said it's an emergency or a safety thing, like having to put her inside of her cage because you're leaving the house, etc.
***Also, try to make sure that there is nothing inside of her cage or outside of her cage that she has access to that is triggering her sex-hormones to rage or that is constantly causing them to be active...The big ones inside of the cage are any type of Boxes, Tents, Beds/Triangle Beds, Hammocks, and especially the "Happy Huts" or "Snuggle Huts", they are not only notorious for causing hormonal-behavior in ALL BIRDS, but they are also quite dangerous and have resulted in the sudden deaths of literally tens of thousands of pet birds/parrots, specifically all species of Conures because they love to get inside of/underneath things that creat a Small, Dark Place. So you need to remove and never put back in anything like this that is inside of her cage that creates a small, dark place she can get inside of or underneath...No beds of any kind, she can sleep just fine on a perch...And the same goes for letting her get underneath things when outside of her cage, such as furniture, behind pillows, blankets, towels, etc. These are all big no-nos, especially with Female Birds, because all of these things not only cause hormonal-behaviors, they also cause the production of infertile-Eggs, and you really don't want that to start happening...
Also, make sure there is nothing that resembles "Nesting-Material" in the bottom of her cage/in the tray, such as any types of animal-bedding, such as corn-cob bedding, crushed walnut-shell bedding, any types of wood-chips, shredded paper, etc. This does the same thing as the small, dark places do...
No petting on the back, wings/underneath the wings, the legs, the tail-feathers, on her belly or around her vent....And avoid all warm, mushy foods...
***Also, make sure she is getting at least a solid 10-12 hours of sleep every night, and if possible get her on a "Natural-Light Schedule", meaning she wakes-up with the Sunrise and she goes to bed with the Sunset, just like wild birds/parrots do (this is the reason why birds in the wild only breed during "breeding-season", they wake-up with the Sun and go to bed with the Sun)...It helps if she can see the light-changes of the sun in the room her cage is in, and right as the Sun sets you cover her cage up with a dark sheet, and then remove it just as the sun starts to rise, so she can actually see the light changes at both times of day...This is a really efficient, quick way of knocking them out of these hormonal-periods...
