Early pregnancy birth control pills are usually taken clinically until the clinical symptoms have disappeared for one week before stopping them. This is because in early pregnancy, the symptoms of pre-eclampsia are vaginal bleeding and pain in the belly, if the above two symptoms are gone, then maintain taking the pill for another week. If you stop taking the medication too early, the symptoms of vaginal bleeding and belly pain may appear again. In addition, if you have the conditions, it is better to go to the hospital for blood test to see if the progesterone in your body will rise after taking the medicine, if the progesterone rises above the normal value, it means the effect is still good. It is also very important to pay attention to bed rest while taking medication.
