Period is late

Ellie

My period is supposed to come yesterday and it’s not arrived it’s usually always on time and I’ve taken a normal test it said negative but I’m not sure if I’m to early or if there is something else going on I’ve had no symptoms of a period at all but I’ve been feeling sick with tender breasts and bloating with heartburn constantly for less than a week It’s been 13 days since ovulation I’m so nervous of being pregnant incase I have another miscarriage
