If a pregnancy occurs then Progesterone hormone is maintained throughout the pregnancy. This is done

If there is no pregnancy then on a hormonoal level what occurs to begin the cycle a new?

Sorry-.-

Yes! The supply of progesterone is maintained by cells of the trophoblast secreting human chorionic gonadotropin (hCG) that supports the corpus luteum.

Quick question duddy, : responsible for morning sickness, and then by the __________. What would this blank be? I thought it might be a hormonoe.

I thought human chronic gonadotropin was responsible for morning sickness as well. However, progesterone might also be the cause of morning sickness. The increase of the progesterone in the body relaxes the muscles in the uterus which prevents early childbirth.  But, as a result, progesterone might also relax the stomach and intestines, leading to excess acids in the stomach and therefore nausea and vomiting.  Another hormone that might be the cause of the nausea and vomiting that comes with the first stages of pregnancy is estrogen.  Estrogen is always present in a woman of child bearing years but it rises rapidly in early pregnancy.

Hope this helps you answer your question.

Thanks man:P
