Overtired baby?

My baby will be a month on Tuesday and she usually feeds every two hours and spends the day Sleeping and if she's up its for a bit and she's back to sleep. Today however she woke up at 12pm and didn't nap all day. She was nonstop crying nonstop trying to sleep. She would doze off and the minute I put her down she'll wake up and start screaming again. I got her to sleep twice but both together were prob like 25 min. She did fall asleep around 7 for like an hour. It was terrible and prob one of our worst days I didn't get anything done just trying to get her to sleep and not completely loose it in her screams. Anybody know how to get her to sleep better or anyone experience this??
