Black object moving across sky Florence sc not sure what it was sept 24 2018

Saw a jet flying over and was watching jet and nearer to me up in sky was a black object floating towards me, but still in sky.  kept moving in my direction again in sky.  i ran inside to get husband so he could see it so he wouldn’t think I was crazy when brought it up so he came out with me and saw it as well.  It kept moving through the sky to our right then continued on over neighbor's house and upwards and then I came inside to ponder what we saw.  not sure if it was a drone a big black ballon or what.  just wanted to share in case someone saw this and didn’t think they were the only one and maybe someone could help me understand what we saw.  now I am creeping out beacause I have no idea what it was.  did anyone else see this?  It was around 6-7:30 I saw.  Sorry not exactly sure about exact time but around those hours.  it was evening before dark on September 24, 2018.  Wish I had recorded it and got a exact time down.  No lights or anything just black.
