Faint Positives?

January 31st miscarried (early probably around 5 weeks, the Dr. couldn't clarify because the ultrasound showed very little) and followed HCG down to 22 about 3 weeks ago. The 1st two showed up that way within the 10 minutes (at 3 was a little more faint) and the most recent was taken before the 10 minutes today. We want to be hopeful but when I tested the week before my miscarriage it was so dark and easy to be sure! Going to wait a day or 2 and test again either way!
