hi tilygirl,

sorry you are going through this uncertainty, i have had 2 pregnancies where the baby measured a week behind and neither one ended well, i hope yours is a different story :-)

in regards to the progesterone i was on it in my last pregnancy and i kept going until the next scan 2 weeks later which confirmed it was over and then i stopped it and the miscarriage started a few days later, so yes for me the progesterone kept onto the pregnancy even though it was over
