I had my first scan yesterday which dated me at 7wks, 6days today. My lmp said I would be 8wks, 3days today and the yolk sac was measuring 9 days. All perfectly fine according to the lady doing the scan and the doctor. There was a strong heartbeat at about 156 beats per minute. Then she said I have a pocket of fluid next to the yolk sac but it's only very tiny but could explain the small amount of spotting I have had. I also have a decent sized cyst on my left ovary. She said this can happen sometimes if the egg came from that side but I need to keep getting it checked at each scan. I have had a small cyst years ago which went away on its own and I wasn't pregnant at the time. Has anyone else ever had this happen? Im worried it may keep growing and get twisted or something awful :'(
