That would be most likely needing to use a progesteron pessary. Usually one in the morning - which is pretty easy because you can just get up an hour earlier than normal then go back to bed for an hour and then the other one is 12 hours later. Some people (myself included) need to take them more often ie. every 8 hours, or every 6 hours depending on levels. This happens after a transfer. Sometimes Crinone is used, in that case you wont need to lay down.
