Worried 😔

 Well according to my app I'm 7 weeks and 5 days pregnant. I've been  having some complications already and I'm having an issue seeing my OB due to not having insurance. I am applying for Medicaid it's just a waiting game at this point. 

 Anyway, I am looking for any insight or advice about what's going on. My problems have been this, about a week ago I bleed lightly for about 7 days. Which I thought it was just a strange period, but come to find out I took a test and I'm pregnant. So, fast forward to a day ago I went to the ER because I had more unusual bleeding and some light cramping. They checked my cervix and it was closed, did blood work, told me to rest drink water, and then I was discharged. Next day I still was bleeding, had some cramping, and at one point a fever. Just very uncomfortable all day. Today I've just had mainly spotting with brown blood. Not so much in pain. I haven't notice any blood clots or ever been in severe pain. 

 Anyone have any idea what's going on? Should I be concerned?
