I’m lost

China

I had unprotected sex both the 20/21 of December he pulled out every time and I had a little bit of blood on my discharge 2 days after . My period was supposed to come the 3/4 of January but it hasn’t . I took a pregnancy test from cvs when I was 6 days late and it came out negative. Now my discharge is white or clear and watery could I be pregnant?
