Am I pregnant or tripping

So I am 12 days late for my period and I think I felt implantation I'm just not sure if it is or not. It was October 16th when the person came in me and I've been getting swollen I noticed it and never told family but my aunt said earlier that "I better not be pregnant because I'm starting to look swollen" I took a test on the 8th but I think it was too early. So am I tripping or??

Edit: I've had breast soreness and nipple sensitivity, getting a lot more tired lately especially when I eat my midnight snacks, I bled a little bit just once and also pain in my lower abdomen. My 5 year old also eats a lot more with me too
