5 weeks and just don't feel pregnant!!

Lori • 9 weeks pregnant , boyfriend left me going through a rough time :(
After my last three pregnancy ending in misscarry. And symptoms started between 4weeks and 4weeks and 5 days with the last three, I'm feeling odd because I have no symptoms this time only bloating and swollen breasts, !! I'm so worried that this will end in a miscarriage as well,! Especially having no symptoms is making me worry! ,, I go for my first scan in 1week 3days n I just feel like I won't see the heart beat!! :(
