Pregnant after miscarriage?

Brittany

I miscarried end of Jan/beginning of feb. February 1st i went for an ultrasound and there was no baby; also the urine test there was negative.

Had my final bloodwork done February 14 to confirm and my levels were in the negatives.

Fast forward to today and i have that queasy feeling , exhausted, breast pain tender nipples all that good stuff. Plus a positive test.

Is it possible that i am pregnant again? That fast??
