Pregnant!!!

Ok I've posted about the same topic before but thought I would update. I miscarried on April 8th at 5 weeks and bleed for about a week and a half. My bf and I weren't trying to get pregnant again right away we were using condoms, but then just started pulling out. About 2 weeks ago I took a clear blue digital to see if my levels were dropping. It came up pregnant but only 1-2 so I figured that was just the hcg working its way out of my body. However, I've been experiencing some pregnancy systems the last couple weeks so took another clear blue digital today and now it says 3+. Could I really be pregnant again that quickly?!!
