Hi K.,
My sister is a member of mamasource and sent this to me as soon as she read it thinking that I may be able to help you. My husband and I of 8.5 years found out that we were pregnant wih our first in September. Being a fraternal twin and having many twins in our family, the first question we had was how soon can we find out how many were in there. My hcg levels came back high, so they became curious as well. We had our first ultra sound at 6 weeks and only 1 baby, but a large placenta. My hcg levels continued to rise and the baby continued to grow and develop normally, but they remained worried about the levels and my placenta. I began showing very early and was VERY, VERY sick. At 12 weeks (5 weeks ago tomorrow), we lost our little baby. The pathology report came back confirming a partial molar pregnancy.
I am not trying to scare you...in fact, this could easily NOT be what you have as it is very rare. But when we were going through this, we asked everyone and everywhere if anyone had any advice and never got any...I honestly believe it would have helped to have known something...anything. It may at least give you something to look into and ask your doctor about. It is rare (less than 1% of pregnancies) so some doctors may not notice it or look for it. In fact, many doctors have never seen it, only heard about it.
I pray that you have nothing like this, but wanted you to know.
Good luck,
M.
