My period should start in 5 days

Amanda • Im a mum and gf!
I had a miscarriage in January and I have since been TTC again,just lately I've had back ache,stomach ache,acne,I've been feeling tired,I'm gassy,I've been stressed,I can't sleep well and I've been eating a lot so is it because my period will start soon or could I be pregnant (it's top to test I know) ???
