AM I PREGNANT?! HELP!!

Mollie

Ok so according to this app I am 6 days lat for my period and I have had super cramps and my boobs are so sore I can’t even wear a bra without being in agony! I’ve had bad heart burn and I constantly need to go to the toilet too! I took a test about a week ago and it said negative but still no sign of a period? I don’t want to tell my boyfriend just yet till I know because he’ll freak out and I don’t want to let him down if it negative, ladies if you could help with advice that would be fab❤️❤️
