It is possible that you are pregnant, even if you received a negative result on a home pregnancy test. Home pregnancy tests are not always accurate, especially if they are taken too early in the pregnancy. To confirm whether or not you are pregnant, you should visit a doctor or a gynaecologist who can perform a blood or urine test to detect pregnancy hormones.

Regarding the effects of Damiana on the menstrual cycle, there is some evidence to suggest that it may have an impact. Damiana is traditionally used as an herbal remedy for a variety of purposes, including menstrual irregularities. Some studies have shown that Damiana may help to regulate the menstrual cycle and reduce symptoms of premenstrual syndrome (PMS). However, it is important to note that these studies are limited and more research is needed to fully understand the effects of Damiana on the menstrual cycle.

If you are concerned about the effects of Damiana on your menstrual cycle, it is best to talk to a doctor or a gynaecologist who can provide you with more information and advice.
