I am 23 years old married for one year. We decided to have our baby this month only and after the D-day I experienced the normal bleeding? This is my first time so I want to know when does implantation bleeding occur after the intercourse. When having implantation bleeding, is it normal to have a little bit of red blood as appose to the brownish color everyone says?Is everything normal with me or I need to be careful with my periods?
