Is it possible to have no sign of pregnancy on an ultrasound and still be pregnant? i've been having negative tests and i got a period. i'd be 7 weeks

Hmmm....: Having a regular period means not pregnant. Having negative pregnancy tests (at 3 weeks after sex or 1 week after a missed period) means not pregnant. Having no sign of pregnancy on a pelvic ultrasound at week 7 means not pregnant. Therefore, no worries about pregnancy this time. If trying to avoid pregnancy, be sure to have a good contraception plan in place all the time, every time.
