I was suppose to start my period on July 16. Well I'm now 9 days late. I have tested twice and both time I got negative. I tested July 17 and 18. Was that to early to test? I have been having nausea in the mornings and sometimes I have diarrhea and sometimes I'm constipated. I have extremely bad bad aches, and slight cramping in my lower abdomen. Does it sound like I may be pregnant?? Should I wait longer then test?? Still no signs of my period. I'm never late. Would really love some advice please!
