Now, a molar or partial molar pregnancy is quite serious. A molar pregnancy is when the mother's chromosomes are somehow 'lost' and the father's chromosomes are duplicated. In a partial molar pregnancy, the father's chromosomes are duplicated again but the mother's remain as well. This can happen with duplication or if two sperm fertilize the egg.
According to the Mayo Clinic, about 20% of women who have had a molar pregnancy will develop gestational trophoblastic disease. This happens when the tissue remains and continues to grow. You'll see hCG levels rise as well. When this happens, chemotherapy may be needed. Very rarely this will turn into cancer. Generally, a complete molar pregnancy can be detected by about nine weeks.
As you can see, you should take a molar pregnancy but I was reminded today of how frequently good miscarriages are misdiagnosed as being molar as in Gabrielly's story. We've been emailing back and forth. She was being misdiagnosed too soon with a molar pregnancy. We've had other similar stories as well, such as Heather's story and Dani's story.
I have a suspicion that some doctors *may* use the molar diagnosis to pressure women into having a quick D&C. Very few pregnancies have ended up being molar in my years on the site. Those women seemed to have really high hCG levels (over 100,000) or other signs (i.e. grapelike clusters, pain, bleeding, etc...). Reading through online literature and it sounds like partial molar and molar pregnancies are often caught at the end of the first trimester and into the second trimester.
How early can a molar pregnancy be caught? This is what I've really been wondering since so many women who are being misdiagnosed with a molar pregnancy seem to be between 6-8 weeks.
I found this study:
A prospective study of ultrasound screening for molar pregnancies in missed miscarriages.
"The diagnosis of both complete (CHM) and partial (PHM) hydatidiform moles in first-trimester miscarriages is difficult. hCG is significantly higher in both CHM and PHM and, in conjunction with transvaginal ultrasound, could provide the screening test required to enable clinicians to counsel women more confidently towards non-surgical methods of management of their miscarriage, where histopathological examination is not available."
For this reason, if there is any reason to suspect your doctor is wrong in their diagnosis, you really might want to consider a second opinion especially during the first trimester. Stay monitored though.
As always (((hugs))) if you are going through this scare.
