Implantation bleeding?

Hey guys, sorry for tmi!! Im 5 weeks pregnant and Yesterday I was using the bathroom and when I wiped, there was a small amount of light brown blood not enough to soil the tissue but enough to cover the top. It wasn't thick, just watery. In the toilet, I saw a small pea sized ball. It looked clear or pinkish with pink lines going through it. This scared the heck out of me and I had a full on panic attack as I thought i lost my baby. My husband assures me its just implantation bleeding and that it was just maybe cervical mucus. So today, all day I've been having very dull uncomfortable cramps, nothing crazy but you can tell theyre there. On a scale of 1 to 10 its literally like .5. Doesn't hurt much at all just very very dull. Ive been feeling a bit moist and each time I go to the bathroom I notice my panties getting more soiled. Its now the afternoon and they look like this. Its a light brown discharge maybe even tan. I just wiped and a little bright red blood is on the tissue. This keeps happening when I'm passing a bowel... Is this normal....? I've read online that some spotting at 5 weeks can be normal... but i just don't know
