Is blood not clotting symptomatic of hiv? I have been extremely fatiqued, hard time sleeping, my periods have been lasting a lot longer than normal and the blood is thinner but my flow is heavy. I have also been having lower abdomen cramping. Also I have been feeling I guess one could say crazy. And have forgotten things from even just the day before. I am just worried. Yet afraid to be tested. If someone has some useful info I would really appreciate it.
