Prolactin
Relaxin
Oxytocin
Lightening is
when the fundal height drops when the baby is ready for birth
Human Chorionic Gonadotropin (hCG)
detected by pregnancy tests from the placenta after implantation
- essential in early pregnancy
Progesterone
maintain uterine lining
relax smooth muscles
help uterus as baby grows
(O)Estrogen
stimulates uterine growth
increases blood supply and helps fetal organs develop
Prolactin
prepare for lactation
- enlargement of mammary glands preps for milk production
Relaxin
inhibits uterine activity preventing premature birth
-softens and lengthens cervix and relaxes joints
What are the 2 biggest hormones that help the body to change for pregnancy?
estrogen
Progesterone
Oxytocin
causes uterine muscle contraction
-triggers prostaglandins to increase contractions further
-induction
- stimulates milk ejection
Maternal changes at 8 weeks cause what hormones to increase
Increase of estrogen and glycogen
Maternal Changes at 8 weeks
- Increase of estrogen leads to
blood congestion and increased vascularity(prominent veins in cervix, vagina, and vulva)

In early pregnancy is a drop in BP normal?
yes due to the sudden start of hormones and slowly going back to normal
The blood volume increase in a pregnancy is required due to the
