Hi, I have gone through your query and understood the concern. If you ovulated as predicted and did not conceive, you should receive your period after two weeks. Blood test cannot detect exact timing of ovulation but follicular studies often do. An even simpler and reasonably accurate test when performed carefully is the recording of the basal body temperature from day one of the cycle. In this, ovulation is indicated by a rise in temperature and this is sustained if conception has occurred. Please go for a pregnancy test followed by a sonogram to plan further management. Hope you find this information useful. Wish you good health.
