Nowadays, when many patients come to our center for examination after pregnancy, we do not check progesterone, but only blood h c g. Many patients are confused as to why we don’t test it now? Here I would like to explain to you, because the value of progesterone fluctuates a lot after pregnancy, and it is up and down, so it is easy to make patients nervous, there are many patients who have a good doubling of h c g, but a slight drop in progesterone, they ask for birth control, in fact, there is no bleeding symptoms do not need birth control. And blood h c g, generally after 2 to 3 days will be doubled, so the good or bad of the pregnant fetus, the judgment is more valuable, in order to avoid the change of progesterone, and excessive panic, so our center now does not measure progesterone.
