Devastated

Got results of my third hcg test. It only went up 120 in 3 days and my spotting has gotten worse today with a few clots ( but the coloring is still Brown which is wierd) things aren't looking promising. (5 weeks 3 days today) repeat ultrasound Thursday to see what's going on. I'm pretty devastated. It's either a miscarriage or an ectopic :'( I don't know what to do with myself. I wanted this baby so bad.
