Miscarriage and feeling pregnant again???

[Munchybaby]

Hi I'm new to this and have a question for you guys. I lost a little one at 81/2 weeks and its been over 2 1/2 weeks since then. My pregnancy symptoms disappeared before my miscarriage and just started a couple days ago, like: sore breast, cramping, tired and sick to my stomach. I have tested a couple time and positive everytime and my hcg levels dropped fast and they were at 23 3 days ago and clearblue hpt showed 1-2weeks pregnant, is that possible?? Me and my DH had intercourse over a week ago not sure what to think also my doctor said I could be in high risk pregnancy:/
