AF 2 days late and loosing my mind

Help! Have your tests been hard to read and then finally get the positive you needed after days??? I’m currently 2 days late which is extremely rare for me I’m always on time and never am late only time was when I was pregnant with my first but with her I tested positive day before/ day of period but was still a light positive. This time I’m 2 days late been nauseous, boobs really sore extremely tired bad back ache and gagging at certain foods which is what I had with my firsts but my tests are so faint can’t tell if it’s the start or indent! Anyone had a positive days into their late periods ?
