I had implantation bleeding..it was more like spotting for me and it was a one time thing. Everyone is different, that was just my experience with it. Good luck!
I heard it'll be light and rather pinkish...
spots when wiping
It CAN be heavy, but for me with both pregnancies where I noticed it, it was a few light spots on the toilet paper when I wiped for about a day. It was bright red, and I didn't see it every time I wiped...but let's say out of 12 times peeing over a period of about 30 hours I noticed spots on the toilet paper about 8 times. But I've heard that it can be heavy...and it's almost always bright red.
