Implantation bleeding does not always occur but it can be one of your first signs of pregnancy. I remember with my first kiddo I had it. Basically, it’s a small amount of blood, as if maybe you are starting your period. I actually thought I had started my period and threw on a pad, but then there was no additional bleeding. That’s implantation bleeding. It is not excessive and it does not continue for multiple days. It’s also normal and healthy, so if you do see it, it’s nothing to get worried about.
