16 week midwife appointment

Lulu

Had my midwife appointment today. Iron level is measuring at 144 which shocked her for a twin pregnancy. Blood pressure and bloods came back perfect so all is good.

She attempted to hear the heartbeats, saying it is possible that with only one dopper we'd only hear one, or we'd either hear both or the same one twice due to the echo.

We heard one on each side which was wonderful, one measuring 154 and the other 147. Could these be the two different babies?
