I've just found this thread as I was googling the same question. I don't know if I have low progesterone, but I was using it as a safe guard when ttc and continued to use it once I fell pregnant as I didn't think it would be a good idea to stop. Well I have the same problem you did Mummylou23. I ordered some more yesterday and I've completely run out today!! Mine won't be here until at least the 21st of Feb. What did you do, do you know where I can buy it? Really appreciate the help xx
