Can anyone tell me what form of progesterone is most often prescribed after CD21 tests? I.e. is it an injection, tablet, cream etc? I had a CD21 test this month and my dr was going to give me progesterone the next day, but I was really sick around Ov time and test indicated I didn't ov then, so it was a little pointless having progest then, so now I am thinking ahead to next CD21 - except I'll leave to go overseas that night - so will have time for the test, but not to got back next day... Can I get my progesterone 'to go'? !!
