white dots

so my husband was out having a cigarette and called me out to look at the weird lights above the tree line. bright lights one at a time about 15  seconds apart. they were in a horizontal line. they got to a certain point and just disappeared. They must've been very high as they appeared as really small dots.  so weird. one just drifting across the sky in a straight line followed by another followed by another etc  there were 11 total. it lasted about 3 minutes. I called my daughter and she said spacex was supposed to launch satellites. so I went in and checked and they were supposed to launch in a couple of days this was the 14th . very odd indeed.
