Guppy dying after birth help asap

[Vegetarian fish nut]

Hi, my guppy gave birth to several healthy fry and now is standing on her head with red strings hanging out of her. Does she stand a chance or should I euthanize her? If so how? Please help ASAP. I am experienced at guppy breeding and have never seen this.

Oh my. I have not personally seen this before, but it doesn't sound very good. If you don't put her down, I have doubts that she will last long on her own. It sounds like a complication from the fry.
Let us know if anything else happens.
