Help would be great!

Destini • Mother of two trying for baby number 3!!!!!

Two days ago I took an 88 cent Walmart test and I believe there was a very faint line, my period is due today but there is no sign of AF. I took the same test with my second morning urine and it look negative to me. We have been trying for a few months so we track my ovulation and cervix position. My cervix this morning was very high ( I could BARELY reach it) and soft. I also have horribly sore boobs, mood swings, nausea, and increased ruination. Is it possible to still be pregnant or should I be waiting for AF to show?
