Hi dear. If u ev already got ur periods by taking withdrawl medicine u most probably were not pregnant. However a urine pregnancy
test becomes positive much earlier than an uLtrasound
showing a sac(a sac seen in uterus
is d first indicator of pregnancy by an ultrasound).u cud ev done a urine strip test n found out ur selves .but even if u ev not done that just go through ur ultrasound report, if it has not mentioned a sac there was no pregnancy. So just relax . N always remember to clear all ur doubts before leaving d doctors office! Take care.
