20 days late but all negative tests ??

tessa

help!! my period is about 20 days late, probably more. i have taken two at home tests but they both were negative. recently i’ve been having on and off stomach aches that make me feel like im going to puke but never do. it might just be stress but i dont know. im 18, a working high school student, no boyfriend except for occasionally hooking up with my ex, and stressed.
