So today I started having some mild cramping , only happened like two or three times . I have been trying not to think about it too much , I have a positive OPK on the 21st , and AF is not due till the first weekend of August . I have also been experiencing more tenderness in my boobs but that usually happens with my period anyway . My cervical mucus has also changed slightly ... could this be early pregnancy symptoms , I am trying not to think about it too much so I don't trick my body to thinking I am .
