Pregnant after my June baby.

So after having my baby , I got my period August 1st and September 1st . Around sept 7th I was having contraction like pains and bleeding would not stop so I took a pregnancy test and it immediately came out negative . A week later I'm still feeling pregnant , still bleeding , morning sickness came around, and I took another test . It came out positive but I was scared I was having a miscarriage. I went to er , they told me it was a 50/50 but I currently was pregnant . I left and went to my obgyn a couple days later to get my hcg levels read again and they were lower then when I went to er . YET they told me I was ok . They went from about 900 to 700 . I bled all the way up to about 2 weeks ago , but I feel pregnant, and I sometimes feel something move . It's not gas , it feels different . I just need advice , I can't go to obgyn rn bc they aren't taking appointments. What should I do , take another test ? Have any ladies bled like a month straight and baby still be ok ?
