Though these tumors can go unnoticed throughout gestation, they are known to cause complications like polyhydramnios, premature delivery, fetal demise, IUGR, and nonimmune hydrops. History is very important and hypertension, advanced maternal age, diabetes, cigarette smoking, and a history of previous abruption are relevant factors
progesterone levels in early pregnancy

Blood progesterone levels start to rise midway through the menstrual cycle, continue to rise for about 6 to 10 days, and then fall if fertilization does not result. The progesterone levels during pregnancy is also crucial for the survival of the fetus, it keeps the uterus from contracting and promotes the growth of blood vessels that give nourishment to your baby during pregnancy

This two-way exchange takes place across the placental membrane, which is semipermeable; that is, it acts as a selective filter, allowing some materials to pass through and holding back others.In the early months of pregnancy the placenta acts as a nutrient storehouse and helps to process some of the food substances that nourish the fetus. Percentages are used to designate the amount of obstruction; e.g., 100 per cent is total placenta previa, and 50 per cent indicates that about half the opening is obstructed

Two characteristics are particularly divergent and form bases for classification of placental types: The gross shape of the placenta and the distribution of contact sites between fetal membranes and endometrium. There are three layers of fetal extraembryonic membranes in the chorioallantoic placenta of all mammals, all of which are components of the mature placenta: Endothelium lining allantoic capillaries Connective tissue in the form of chorioallantoic mesoderm Chorionic epithelium, the outermost layer of fetal membranes derived from trophoblast There are also three layers on the maternal side, but the number of these layers which are retained - that is, not destroyed in the process of placentation - varies greatly among species

I still thought my implantation bleeding was a period, and it wasn't until my first ultrasound that I discovered I was a whole month further along than I had thought I've had implantation bleeding with both previous pregnancy's. I'm confused, everyone says implantation bleeding does not look heavy and is only a few spots, i have had this for two days! Every time i wipe it looks like alot of blood, but there's nothing on the pads! My husband and I have been of and on trying to get pregnant this year..every month i know when my period is supposed to begin, and then i hope for the best, a YES...but the last few times i have gotten my period as usual....this time I am still waiting my period should be her on Dec 13 2010

reproductive system: Definition from Answers.com
http://www.answers.com/topic/reproductive-system Competition: low
If no fertilized egg is present toward the end of the cycle, the thickened endometrium degenerates and sloughs off and menstruation occurs; if a fertilized egg is present it becomes embedded in the endometrium about a week after fertilization. The seminal vesicle, which produces nutrient seminal fluid, and the prostate gland, which produces alkaline prostatic fluid, are both connected to the ejaculatory duct leading into the urethra.The first stage of the male sexual act, erection, results from nerve impulses from the autonomic nervous system that dilate the arteries of the penis, thus allowing arterial blood to flow into erectile tissues of the organ

Just remember that if you test every day from five days prior to period or a week after (please be responsible) the pregnancy will be there regardless!!! Best of luck to all!!!! Comments It takes a minimum of 10 days after implantation to test positive, on a blood test a urine takes longer. Cramping just before and after ovulation is normal; this is because the egg actually bursts out of your ovaries (yow).but the cramping may be a pregnancy if you have missed your period or it was light
