I am not a certified medical doctor. All medical advice I give here is my own, which may not be correct. You should talk to your own physician or an experienced sexologist before making any decisions.
What is the purpose of hormones? When you are pregnant, sex hormone levels are very high. A person with a normal reproductive system needs a lot of hormones in order to function normally. Hormones are vital for maintaining your baby's health and ensuring normal development. They can make the uterus contract, which helps the baby develop properly. They can also make the cervix dilate and decrease the amount of time your uterus is open. When you are in menopause, the hormone levels drop dramatically. The lack of hormones makes the body grow more slowly, making it harder for your uterus to contract and to keep the baby inside. There are various different products that contain hormones to help your body function properly, but none are 100% effective.
There are also many different things that can affect your menstrual cycle. One of these is smoking. There are a few products that contain nicotine. These products may help you get through your next menstrual period, but may have unintended consequences.
