Flats do come in swarms. Sometimes for a reason, sometimes not.

Just last week I had two flats on my commuter bike. Totally unrelated events.

Before that I can't even remember when I had a flat tire last. I think it's the time I had a slow leak, my Dear Partner decided to change it (against my will), and he caused a big pinch that ripped the tube and exploded less than a foot from my ears. Ouch!!!

This being said sometimes there's a reason for multiple flats. When you change a flat you should thoroughly inspect your tire (sometimes little shards of glass hide in the rubber and you don't see them unless you really check closely), and if you keep getting them also have a look at your rims. Sometimes rim tape slides...

Good luck!! Do learn the skills (it's really empowering), but do not worry too much.
