Weird twitches??

Hey yall!! My husband and I just found out we’re finally having our first baby after almost a year of trying! Due around October 28 according to our apps. I’m 4 weeks and 3 days today and just now started noticing some weird twitching on my left ovary area. Don’t know if it’s actually my ovary or something, or maybe just a muscle on top twitching but it’s been happening on and off for the last 20-30 minutes. I’m not really concerned just thought it was interesting and wanted to know if anyone else has had this happen. Thanks!!
