Second Sac Increases Risk of Miscarriage

Dear Ms Ultrasound,
My name is Royann and I am just about 7 weeks pregnant. I just had an ultrasound and the doctor said that the baby looked great and had a strong heartbeat, but just a couple inches away from the baby is another sac that looked like it had some fluid in it and maybe a yolk sac.

The doctor didn't know if this was a subchrionic hematoma or if it was going to turn into another baby. I have another ultrasound in two weeks. He said that my chances of having a miscarriage are greater. Could you please tell me why that is?

Could Oversized Uterus Indicate Twins?

Dear Midwife,
I am 15 weeks pregnant with my first child. I regularly see my OB/Gyn each month but he hasn't measured the size of my uterus yet. I have been reading several pregnancy books and they say that at 15 weeks my uterus should be easily felt 3-4 inches below my belly button. My stomach feels hard starting at my belly button, but I'm not exactly sure what I'm feeling.

Urine Test During Pregnancy: Urinalysis

A urine test is a routine test used by your healthcare provider as part of your prenatal care. Although urine tests are used in screening for pregnancy, this article is discussing urine tests as part of your routine prenatal care.

How is a urine test performed?

Your healthcare provider will ask you to collect a small sample of clean, midstream urine in a sterile plastic cup. Chemically prepared testing strips are dipped into your sample of urine to screen for certain indicators. More in-depth analysis may be done by having your urine sample assessed by a laboratory.
