Welcome to ehealthforum.
If you are pregnant and suspect having twins again, then request your gynecologist for a scan at 6-8 weeks which will show you are having definite twins. Other tests include a Doppler scan to locate heart beats (it would locate 2 in twins are present), high AFP and HCG levels. Excessive weight gain, morning sickness and fatigue also indicate twin pregnancy.
Take care.
