Weed ID Help in St. Aug lawn

Can anyone help me identify this weed? It’s all over my front and backyard. I put down a preemergent in Oct and Feb and fertilized with a quick green up in early March and a slow release the first week of April. Now these things are everywhere and growing much faster than the actual grass.

Update:
Glad I didn’t try to get rid of the grass in my grass. Leaving this up so everyone can have a chuckle. If it wasn’t already obvious, this is the first year I’ve ever cared about my lawn or done anything other than mow it. This board has been a great reference and I appreciate everyone's help.
