Re: Do any of you know what this was?
Could be BH or ligament stretching. You aren't too early for BH, but generally this early they don't hurt - they are just uncomfortable. You can mention it to your Dr at your next appt or call if you are worried about it or if it keeps happening - especially if it is painful. If you are experiencing painful cramping though then I would probably call to make sure its normal and to be on the safe side.
