still bleeding?!?!

so i posted on here not 2 long ago about bleeding during pg and  i am still bleeding not bad, but enough to wear a panty liner, its mainly bright red or brown and it usualy goes away at night and comes back during the day! but i had my period i thought dec. 11 thru dec. 16 and bd on the 17 and then started bleeding again on the 17 and i'm still bleeding! i did go to the er b4 i found out i was pg cause of the bleeding and i had really bad period cramps, they told me i was pg and they did a US and said it was too early to see anything and they scared me by saying it could be ectopic! but i haven't had any real bad pain since! and they checked my hcg levels and they were 217 and said i was bout 4 weeks 2 days later on christmas i had to go back and they were 568 so they went up but i'm still worried! i have an appt but have to come up w/ 350 dollars if i'm not on medicaid! and i want to wait til we get our new house hopefully this week so i can try to get on medicaid then! idk my sis said she bled for the 1st couple months of each of her 6 pgs, this is my 2nd and never exp. anything like this. also i am feeling a lil pain in my lower abdomon but i heard thats just ur uterus expanding! i do have ovarian cysts but could that be making me bleed this long? will it ever stop or what? lol its just annoying! has this happened to any of u? or happening now? if i was 4 weeks then i'm 6 wks now!  i called my doc and he didn't say anything about the bleeding but said he liked how my levels r going up! i just hope and pray everything is going to be fine!! my husband said its a girl and she's already giving me trouble!! lol
