Can some implantation bleeding look like you having your period?

It depends. Its generally a little lighter and a lot shorter. if you typically only have light periods for about 3 days then it could look similar. Implantation bleeding shouldn't last more than a few days around the time ovulation would normally take place and it can be either red or brown. Every woman is different though so a pregnancy test would be good afterwards. Just remember not to psych yourself out. Extreme stress can cause some of the same symptoms and cause missed periods.
