Period questions?

Andrea❤

I didnt clot at all my last period, it was 4 days long which is shorter than my normal cycle, it was 2 days late, and i was lucky to fill a pad a day and i never filled one at night. Could that be pregnancy? I know some women get their "periods" while pregnant. Btw my partner and i are very sexually active and had sex almoat everyday of my fertile window before my "period". Im not under any stress and i wasnt at the time either. I did take a test this morning and got this but i just want some insight from you other lovely ladies. I will be going to the doctor based off this test.
