Possible drone/UAP?

Possible drone/UAP?
So I’m right on the border of Waco/McGregor Texas and tonight I saw something I think. This evening I decided to go in my parent’s backyard since I’m home for the holidays and live in Baltimore. My youngest her brother and I are looking at the stars and we both see a flashing star it’s just moving up and down flashing red and blue. Honestly my first thought was just police helicopter because I’m from Baltimore city and that’s not uncommon to see. However it made zero noise and wasn’t actually moving horizontally? It was blinking and just moving up and down vertically (if that makes any sense?). Idk my brother and I got weirded out bc we’ve seen the news all on the drone and I’ve been a long time enjoyer of UFO/UAP stuff so we came inside. 

Basically if anyone can either confirm it’s one of these weird drones, or reassure me that it’s probably nothing I’d appreciate it bc I have a slightly scared 6 year old and 22 year old (myself).
