Miscarried once... Pregnant again?

Shannon
In jan I had a miscarriage. I was suppose to get my blood tested until my levels were back to 0. My last discussion with my doctor ended in needed one more prescription going back to the hospital and back to the lab to monitor me back to zero. I was over it. I needed surgery bc it didn't pass itself. I was sad and tired of the process and decided NOT to go back. The level was at 16 in February. I've had 3 cycles past then... Today I took a test and it said we were pregnant. I'm afraid to be excited bc I never made sure I got to zero??!! What do u guys think? Are we ok? It's been close to 3 months. I can't deal w the disappointment again.
