Just a quick question ,

Im currently overseas , and the level of care here ( Poland ) is RIDICULOUS.
Anyways , im 17 weeks preg. Everything was running well , until I decided to go to a new doctor today - she did an internal told me all was well , then did an ultrasound ( on a machine from the Flinstones era ) .. and told me my Uterus was small , it wasnt as it should be at 17 weeks.. but roughly for 16 weeks... ? ? ? What the hell is this woman on about ? Im stressed enough as it is , because im far from home , and my belly just isnt growing and now THIS ? ? ( everything was measuring to date at my earlier ultrasounds with another doctor ) .
Any advice on this would be much appreciated.
Coz im one paranoid mama
