No there, is no specific blood test to check for twins, although higher than normal HCG levels in a blood test may be because of twins, although it is no where near accurate for predicting a twin pregnancy.
Spotting is not an indicator of twins. Many women with a single fetus spot during the first trimester.
No it's usually not until around 16 weeks, same as with one baby.
First trimester: 1-12 weeks of pregnancySecond trimester: 13-27 weeks of pregnancyThird trimester: 28-40+ weeks of pregnancyThere are three stages of pregnancy which are divided into trimesters. The first trimester covers week 1 to week 12, the second trimester covers week 13 to week 28 and the final trimester covers week 29 to week 40.
I would say that if as long as you can remember your family has been having twins, triplets, ect. I would say it runs through your family's blood.
Mrs Johnstone had 7 children first but then gave birth to twins. one of the twins she kept herself and gave one away to Mrs Lyon's.
There are no twins in Mindless Behavior. None of the four boys are related by blood.
The twins are emo. If you don't believe me check Google.
Yes, paternal twins can have different blood types. This occurs when the twins inherit different combinations of alleles from their parents, as blood type is determined by multiple alleles (A, B, AB, and O). Since each twin can receive different alleles from each parent, they may end up with distinct blood types despite being twins.
Hyperemesis is seen more often in first pregnancies and multiple pregnancies (twins, triplets, etc.)

The other parent must have type A or type AB blood. That combined with yours to give genotype AO, which gives your twins type A blood because O is recessive. Blood is made in the bone marrow. (someone else will have to help about rhesus factors, I don't know enough about them)
