Fluttering In Lower Abdomen (Read Description)

So, I was just laying in bed, watching TV- I started to get this heartbeat/butterfly-like fluttering in my lower abdomen, just above my pelvis, that only lasted about one minute. Now, I keep getting the same feeling every few seconds, but it only lasts like, literally half of a second. Have any of you ever had this feeling before and found out why? If so, what was it? (I also have an Ovarian Cyst on my left ovary ATM; I have them pretty bad every month and have never felt anything like this.. Not really worried about anything, just very curious.) TIA!
