I took one of those Amazon pregnancy test that comes in a pack of 20 just a minute ago, and the control and test line came back very dark and solid, my period is expected in 2 days. I took a dollar tree test last Thursday and the test line wasn't as dark, it was very faint, I downloaded several <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">pregnancy apps</a> just to see how far along I'd be, and it says I'd be right at 4 weeks today. I know with my miscarriage back in December the tests never got darker, and I miscarried because my hormones weren't rising accurately. I haven't been able to get into the doctor to have a blood test to check my levels but last Friday at the ER they were 82, and the docs said they couldn't see anythig on the ultrasound, probably because it was too early. Do you think we are actually possibly having a successful pregnancy so far?!
