Actually pregnant? Or something else?

 I had a miscarriage early in January. I had my period again on February 10th but not sure when I ovulated after that. Now my period is late, I'm having pinching and dull cramps, I've been peeing A LOT, I feel hungry and faint every few hours I don't eat, and I've also been getting indigestion on and off. These are all symptoms I had when I was pregnant before except for the pinching pains. I took a home pregnancy test this evening but it was negative. Anyone have any insight?
