Don't know what tab to ask this in. Questions about negatives

Brianna
Ok, so hubs and I have been trying for a baby for 11 months:) I was wondering if it's possible to be pregnant even after AF DOESNT SHOW HERSELF and I've had all negative results. I'm 12 days late. And there are no signs of AF showing up. I've had slight cramping that kinda feels like someone is pulling on my ovaries ( not normal) but no blood. Breasts are not sore but I have swelling in me feet and ankles. I just really want this baby.
