Wtf!!!!

Ok so I have been having symptoms, as I've previously posted. But tests are still giving me a BFN. However, my period is due in under a week. For shits and giggles I decided to take an ovulation test, because I hadn't gotten my fertile window this month. It said yesterday was my peak day. However, the one I took today is reading the same way. A friend brought it to my attention that opk tests can say positive if you're pregnant because they don't differentiate between LH and HCG. So now I'm just extra aggravated that I need to wait for my period to show up.
