If you don't have P4 issues, generally it's not going to matter a hell of a lot if you started one day late. The P4 supps are a precaution only in those cases. It's probably why you're only on one Crinone application a day (so was I when I was on crinone ). The cycle we fell pg, I had so much P4 in my system that where most pg women have levels of about 100 at cd 28, mine was 1000+ at cd 27.

Don't stress hun, it's only an issue if you have major P4 issues.
