Flea bites?

I can’t really tell if they’re flea bites or something else but it started off as tiny welts and I started my bed with raid bed bug spray just Incase it was bed bugs. But there’s only 4 bites on me. And they’re not in clusters. Just really but welts and they don’t itch that much only if I accidentally brush up on them with something. My only thought is fleas Bc I had got some cats last month and they had fleas but I didn’t get bit so idk
