So my period is currently 8 days late and I've taken 3 pregnancy tests (which have all come out negitive) but I still haven't gotten my period. I'm also getting a whitish sticky discharge which I usually get before my period but then again still no period. My period is usually regular about the same time each month but there have also been times when my period won't come for like 2 months so idk what to think, suggestions? Advice? Has this happened to you before?
