I need advise

In February I had a miscarriage and in March my period was a little off but this is pretty normal after a miscarriage. But the past two weeks I have felt very nauseous, bloated, cramps, falling asleep hours before usual and taking naps (which I rarely do) and a little gassy. I’ve taken 2 hpt but both were negative. Someone give me advice. Idk what to do or think. I’m now 4 days late and I’m not sure if it’s because of my miscarriage or maybe I’m pregnant.
