An over-the-counter home detector that detects the strong LH surge that occurs before ovulation. A blood test of progesterone — a hormone produced after ovulation — can confirm that you're ovulating. Other hormone levels, such as prolactin, may also be checked. Imaging of the uterus and tubal. During hysterosalpingography, an X-ray dye is injected into the uterus and X-rays are taken to detect abnormalities in the uterine cavity. The test also determines whether fluid is passing outside the uterus and spilling out of the fallopian tubes. If any abnormalities are found, you'll likely need further evaluation. In a small number of women, the test itself can improve fertility, possibly by pumping out fluid and opening the fallopian tubes. Ovarian stock check. This test helps determine the quality and quantity of eggs available for ovulation. Women at risk of depleting eggs — including women older than 35 — may have this series of blood tests and imaging tests. Other hormonal tests.
