Hi all, sorry I'm late
It would appear the fish has had her egg sac rupture and the eggs are being expelled. If the egg sac in her body did actually rupture she probably won't survive the next 24 hours and if she does survive she probably won't breed again.
Female Livebearers have a separate compartment used to house the developing eggs and young. On rare occasions the lining of this sac/compartment can rupture and serious internal complications arise.
You mentioned a small amount of blood when it first happened. What appears as a small amount of blood to you and I is in fact a serious amount for a 2 inch fish.
Keep her in a nice calm place without other fish, (especially male livebearers) and see how she goes. If she looks worse then euthanase her. If she survives then keep her away from males for a month so she can heal up and recover from the ordeal.
