Possible chemical.

Today I’m an estimated 5 weeks 2 days. I found out exactly 1 week ago when I got a faint positive. I’ve taken a bunch of test well came out positive including a digital that I took 2 days ago saying pregnant..... about an hour or two ago I started cramping, nothing severe, but I also noticed my breast haven’t been as sensitive so I decided to take a test and it I noticed my lines were really faint so i took a digital and it came back not pregnant.

How long does it usually take for bleeding to start? The cramping isn’t severe but it’s enough to notice and it’s been consistent as well as my lower back...

I didn’t think I’d be this sad because I know how high of a risk a chemical is especially for your first pregnancy and I kept myself as disconnected as I could but when I took that digital two days ago and finally seen pregnant it changed something in me and now my heart is just shattered because we have been trying for a year and a half.

Any advice especially for us continuing TTC would be greatly appreciated.
