unfortunately progesterone can mimic a lot of pg symptoms - raised temp, the cramping in your abdomen - in some people, if they're sensitive to the meds, if can even cause nausea!

it SUCKS that you cant say what is from progesterone and what is from pg - but yes, many of us have been through TWW on the pessaries and not been able to tell one way or another if a pregnancy has occurred cos you feel the same either way. HCG doesn't start to impact you until later on when it is in higher numbers - the progesterone is responsible for most of what you feel very early in pregnancy....
