water leaking?

I'm a little over 37 weeks and while I was walking downstairs to my basement I felt an odd sensation in my stomach and then felt like I may have peed myself a little. I went back upstairs to check and there was a damp spot in my underwear a little bigger than a quarter. It didn't smell like urine and I didn't feel like I peed because no pressure was applied for it to happen it just happened. It happened two more times after that but didn't feel like a gush, I could just see damp spots in my underwear when I used the bathroom. It hasn't happened since but that was around 11am today. I decided to still go to work because I thought I'd anything being on my feet would help move things along. I've been having mild period like cramps and baby girl is moving like crazy. What are the odds that my water could be leaking versus possibly just peeing myself? I haven't had any issues with incontinence throughout my pregnancy so that's why I'm leaning towards it possibly being my water. Thanks in advance!!
