I : I would say that your symptoms will not be relevant to whether or not it is possible (sorry) because it is possible, though at 8 weeks not probable, for this to be the case. I would expect the potential to be much higher from 5-7 weeks. Ask the doc who did the ultrasound and share your concerns. Best, it ;-).

Not likely: By 8 weeks, a twin pregnancy will show two fetal poles by good quality ultrasound. If you are overly concerned then a repeat ultrasound at 12-18 weeks may reassure you, especially if you are having unusual pain. Sooner if pain is truly unusual.
