Is it possible to get your period and still be pregnant? is so, is there a way to know about it without taking a pregnancy test?

Yes: Some women have some bleeding in early pregnancy that feels like a period. The only way to be sure is with a pregnancy test. Other signs of early pregnancy include tiredness and soreness in the breasts.

Ultrasound: If you think you are at 6 weeks or longer pregnancy you may get an ultrasound, though a home pregnancy test would be much easier.
