Possible pregnancy after miscarrage

Haley
So it's been a few days over 4 weeks since I had a miscarriage at approx 7 weeks, and only bleed for 1 week. I knew I was pregnant for approx 3 weeks before a test even showed positive because of how I felt. (Sever tender breasts that feel "fuller", food cravings etc) Now I'm having those same symptoms again for the past week but yet no positive test. I honestly don't know what to think ot make of this. If someone coukd give me some opinions i would greatly appreciate it. Thanks ladies.
