A girl ?

I wanted to ask you girls a ? I have been feeling sick for the last few weeks. And I missed my period last month. After exercising last night I had some bleeding.Is it normal to have bleeding at the beginning of a pregnancy? Because im not sure if its pregnancy or just my period starting.

    Try not to do to vigorous exercise, it could be implantation bleeding.
