probable miscarriage

Kate

hi ladies! so recently I got my bfp. shortly afterwards I began bleeding and figured it was a chemical as i have already had 2 mc and have been losing hope since. a week after I started bleeding it wasn't letting up so I took another test and again bfp. I've recently stopped bleeding and still having positive tests. I went to my Dr and have been getting my hcg levels checked every 48 hours. the first one was 161, second was 209, and most recent was 269. the numbers aren't doubling like they're supposed to but they are increasing. anyone have anything similar and had a positive outcome? tests at home seem to be getting darker, but it may be because I feel like I'm going crazy. thanks in advance
