Here is some input and advice from FAQ Farmers on the subject:
nope, it happens often...
A phantom pregnancy, or pseudocyesis, is a condition where a person believes they are pregnant and exhibits pregnancy symptoms, but there is no actual pregnancy. If a pregnancy test is positive, it typically indicates the presence of the hormone hCG, which is produced during a real pregnancy. Therefore, a positive test generally rules out a phantom pregnancy, as it suggests that a biochemical pregnancy is occurring. However, false positives can occur in rare cases, so further medical evaluation is recommended for clarification.
yes because to have the phantom pregnancy your body secretes pregnancy hormones which is what pregnancy tests look for
Yes. In a phantom pregnancy, the body is tricked into feeling like it is pregnant. Consequently the same hormones present in a real pregnancy will be present in the body of someone who is undergoing a phantom pregnancy, and these hormones are what a pregnancy test detects.
IF YOU ARE SURE they are all girls then one is probably having a phantom or false pregnancy.
You die
A horse who is experiencing a phantom pregnancy will have symptoms of an actual pregnancy. These symptoms include the horse being tired with a puffed up stomach.
Nausea during pregnancy is caused by changes in the hormone levels in the body during the early stages of pregnancy. It usually happens early on in the pregnancy.
Yes; it is called a phantom pregnancy. Which basically means that it is all psychological. Either you are very afraid, guilty, paranoid etc. about being pregnant that you think your mind into being pregnant or you want to be pregnant to bad that you fool your body into thinking that you are pregnant. You will experience pregnancy symptoms and can even lactate during a phantom pregnancy.
Nothing
The only difference between a phantom pregnancy and a real pregnancy is that with a phantom pregnancy you are not actually carrying a baby and you will usually have a period and a negative pregnancy test. You will have the same symptoms as a regular pregnancy and they can last at least as long as 7 months.Scroll down to related links and look at "False pregnancy - Wikipedia"
