Bleeding!!!!

So I'm about 8 weeks tomorrow I've been light bleeding for 5 days now I've been to the er twice ....I've been passing some tissue .....I've called and went to my ob/gyn ...they say then can't help cause I haven't had my first appointment with them.....and it s not until the 17 of Aug ...I'm just so frustrated already....and when I go to the er they say the baby fine and I need to follow up with my ob/gyn ...I don't know if i should go back to the er again or just wait it out.... anybody going thru this ?????
