If I was pregnant for such a short time, how many hormones would there be a week after a miscarriage? posted 07/25/2012 by a BabyCenter Member Was this answer helpful? posted 07/25/2012 by a BabyCenter Member Was this answer helpful? 0 out of 0 found this helpful I had a similar episode earlier this year. On Feb 15th I got my first positive pregnancy test after trying for a year and a half. On Feb 21st, I miscarried and had what my doctor called a "chemical pregnancy".
