Looking for some reassurance from anyone that's experienced similar. Expecting dcda twins and twin 2 is measuring smaller than twin 1. Had a scan at 30+2 today and twin 1 is 13lb 4oz and twin 2 is 2lb 13oz. Twin 2 also has a high PI (over 95th centile) so I'm back for that to be checked on next week. It was high a couple of weeks ago and then normal the week after. I'm worried because twin 2 is just below the 5th centile. Any advice?!
