My grape juice started fermenting on its own

Im not "new" to brewing wines but im not exactly a professional at it either.
I have brewed a few alcohaulic beverages in the past experiemtning with orange juice (terrible idea) and apple cider.

but the other day i grabbed a bottle of grapejuice that i forgot i had in my garage it had been siitting there for atleast 3 weeks and i noticed it had a bit of a wine taste to it and i quickly realised it had started fermenting.
so i bottled it all up =D

now i know its not brewers yeast going to town in there, and im not worried that the end product will be gross i just want to know if the end product could be unhealthy for me
Will it be ok to drink this thats all i want to know

It won't hurt you in any way except for one. If you bottled it before it was finished fermenting, you very well could have made yourself a bunch of bottle bombs.

Be careful with those bottles!

alright thanks ill be sure to keep bleeding the pressure and eventually move them into a high pressure soda bottle or something
