Hello, thanks for using Health Care Magic.
is a hormone produced in the body which helps in the menstrual cycle and during pregnancy
. During pregnancy, it helps in maintaining the pregnancy and in embryogenesis of the developing fetus. Inadequate or insufficient amounts of progesterone is a common cause of abortions during early pregnancy.
As such, progesterone is given in early pregnancy up to 13 weeks of gestation so as to prevent abortions due to insufficient progesterone.
In your case, with the notion of crampy pains and spotting, it is certain that your doctor was managing you for an insufficient progesterone and that is why he put you on progesterone. Progesterone is safe in pregnancy and its deficiency is even a major problem incompatible with pregnancy.
Best regards and hope this helps you
