Had temp rise on unmedicated cycles. didnt do opk. thought hcg shot would give a + anyway. taking progesteron since 2.5dp shot 3 days now no temp rise?

Clarifying: OPK signals ovulation by detecting the hormones estrogen & LH which are high right before ovulation. It doesn't detect the presence of HCG, although a typical pregnancy test will do so. Progesterone won't help you conceive. Although it helps to maintain an early pregnancy once you've conceived and will set the stage for a menstrual period if you haven't, it actual inhibits ovulation.
