Is it possible???

My period was late 2 weeks after having unprotected sex 2 days before and on the day my period was due. I thought I was pregnant and I felt like I had all the early pregnancy Symptoms I usually do but then my period finally came 2 weeks later. I never got a + test but figured it was to early. I might be imagining things but I feel like I see the faintest line(could very well be going crazy and there probably is no line there 😂) but thought I'd ask you ladies anyways.

Is it possible I could be still pregnant even tho I had me period(just ended yesterday)??
