It is important to rule out the presence of pregnancy during menstruation, because a small amount of bleeding can occur when pregnancy is in the bed. If you are not pregnant, you can take oral medication such as motherwort granules or motherwort combination, which can regulate your menstruation and increase the amount of menstruation. However, it is also necessary to look for other reasons for the low menstrual flow, such as the presence of endocrine hormone disorders, increased prolactinemia, progesterone deficiency, or polycystic ovaries, all of which can cause low menstrual flow. If you simply increase some drugs or increase the amount used, the effect may not be particularly good, so it is best to take oral medication to target endocrine hormone therapy, in order to avoid the continuous occurrence of low menstrual volume in the future life, which will have certain effects on the body.
