Anyone have Contractions all day one day the none the next?

I was having contractions yesterday, some got really painful. They were 5-8 minutes apart for 2ish hours. I was convinced I would need to head to the hospital. Then they backed off and were sporadic the rest of the night. Now today I have had a few here and there, but nothing consistent at all. Anyone experience this? Could labor be starting soon?

Thanks!
