Hello, and I hope I can help you today. There are two possibilities that could be going on in your situation. The first, is that the pregnancy is actually younger than what would be expected based on your last menstrual period. The second, unfortunately, is that the fetus died during your six week of pregnancy and is just still remaining inside you. The tissue surrounding the pregnancy is what produces hormones that still give you pregnancy related side effects, even if the fetus is no longer developing. Furthermore, there is nothing that can be done to alter the potential outcome of this pregnancy. If it is destined to be a miscarriage there is no medical treatment that can prevent it. So there is no medication that can help the baby to grow or develop normally if it already has been lost. The only thing the can be done, is to watch and wait and see what happens. I would recommend that you have an ultrasound repeated in two weeks to see if the fetus has grown and has a heartbeat. If not, this pregnancy is a miscarriage that is just not passed yet from the body. The positive news, is that even with two miscarriages, there is a greater than 80% chance that the next pregnancy will be completely normal. If this turns out to be a miscarriage, your doctor may want to do some simple tests that can evaluate if you have any other risk factors that might ve caused this to happen. I am very sorry about your situation, and I hope everything works out for the best. Best wishes, Dr. Brown
