Hi there I'm due for my period soon but I'm feeling sick a lot and my stomach feels like its bloated and I did 2 home pregnancy tests and they have came back positive and I have some back pain could I be pregnant

If you have had positive hpt's then you are most likely pregnant. I would suggest getting an appointment with your doctor to confirm the pregnancy and start your prenatal care.

I also have gore stones in my gore bladder could that affect the pregnancy tests coming back positive and I don't have any signs of my period and I still feel sick

The hormore level present in pregnancy is specific,however there are always exceptions.

As advised above,go to your doctor for a blood test to confirm.
