I have a feeling that I'm pregnant but I tested and it said it was negative on a pee test. I have been getting lightheaded, bloated, I'm eating more than normal, jittery, darkened red nipples, squishy breast when they are usually firm, and they have grown fuller, headaches, cramps, slightly nauseous, I was 2 days late for my period, and had highlighter yellow discharge, then started my period, which lasted for 2 days. My mom said she didn't develop enough pregnancy hormone to show up on the per test and that she had a small period with two of her children. Even after the period I am still having these symptoms. What do you think? Is it possible for me to be pregnant?
