AF due tomorrow ..

Let me just start off saying I greatly enjoyed the year and three months that AF didn't come and visit . I got pregnant last October , had William in July and since I'm still BF AF has been very irregular . Finally had my first PP visit on January 31st . And imediantly we started TTC . AF Is due tomorrow . But I've had four positive opks in the past four days . And one very faint pregnancy test . I'm hoping that we did conceive . I'm extreamly naseous tonight and don't feel all that great . I've been mildly crampy on and off and  get light headed at times . So probably going to re test on either Saturday it Sunday
