Early ultrasound: An ultrasound performed in the first trimester can confirm twins.

Pretty early: You can sometimes know you're having twins early based on your serum HCG levels (they are higher with twins) as early as 4 weeks after your period.

Yes: There is a gene that increases the chance of fraternal twins. This is not the most common reason for twins, though, so for most women twins is a random event, occurring about 1:100 pregnancies. Fertility treatment, of course, can increase this risk. Identical twins are not related to any gene. ...Read moreSee 1 more doctor answer
Depends on treatment: Clomid (clomiphene) ovulation induction may pose a 5-8% multiple pregnancy outcome. Injectable FSH treatment carries a higher risk of approximately 25%.

I had an u/s done at 6 weeks. I thought i was 7. Found out it was twins. Found no heartbeat or flicker. Is it to soon?
Talk w/ Dr: The Dr who did the u/s is the best to ask about the results - that's part of the procedure! If there was anything drastically wrong - even mildly off - they'd probably have told you.

Faternal twins at my last u/s they where in the t shape now I'm feelings kicks all over are they able to move all around I assumed they would stay t ?

There growth will be monitored by your OB. There are standard growth curves. Full term for twins is frequently 38 weeks. Best wishes for a successful pregnancy. ...Read more
Donor in TTTS.: Stuck twin is a descriptive term for the donor twin in a case of twin-to-twin transfusion syndrome (ttts - seen in 15% of all monochorionic/diamniotic twins which comprise 1/3 of all twins - identical in lay terms). ...Read more

The condition is called twin to twin transfusion syndrome. ...Read more
Careful what U wish4: Carrying a twin pregnancy is not something anyone plans - and for good reasons: it is fraught with risks for fetal loss, preterm birth, hypertension, diabetes and maternal health problems that are not desirable. You can only take Folic Acid 1-5 mg daily and try to conceive naturally - 1% of the time twins result as an accident of conception - not a planned outcome. ...Read more
Twins: There is no way to ensure that you have twins. They can run in families so you might have an increased possibility of having twins. And people that have had fertility treatment have an increased risk of having twins. It can happen when two eggs are released by the female at ovulation or when one egg splits after fertilization in which case the babies are identical twins. ...Read more
Rare - bad!: Locked twins are monochorionic/monoamniotic twins that have locked heads so that the breech presenting one cannot be delivered because the cephalic second twin is holding it in utero by locking their jaws. Extremely rare and potentially lethal, unless a cesarean section is promptly undertaken. ...Read more
