Have you scheduled an appointment with you OB/Gyn yet? I think you are well over due for a visit there (for a blood test). That's if you still haven't had your menstrual since December. Good Luck to you.
if u have had unprotected sex and u were ovulating...there are high chances that u are pregnant...plus u have a implantation symptom aswell...it u hv passed ur period date but hpt still showz ngtv wait for a few dayz if still ngtv n no period itz best u tale a blood test...
Go to the doctors and make sure if u haven't got a regular Pd since Dec. Its better to go to the doctors just be save
