Am I pregnant again ?

Brittni

On 8/9 I had a d&c; for a missed miscarriage. I should of been 11 weeks. I basically miscarried at 8 weeks. So on 8/29 I got a blood test my level was at 76, on 8/31 I was at 45. That's a big drop in 48 hours. So I'm assuming I wouldn't went to 0 within the next 2-3 days. So on 9/7 my level was at 15. I'm nauseous here and there and extreme bloating towards end of the night. Also a lot of gas. Based off this chart do you ladies think this could be a new pregnancy. Because I would only be a week or so if my levels dropped like I was thinking ? I'm going back Thursday again to see is they increased or decreases.
