anything??

AF WAS DUE on Saturday no sign of her at all was having cramps at 6dpo all the way until 11dpo than at 12dpo and 13dpo I had bad left lower side pain kind of felt like ovulation cramps , sore boobs, headaches, cranky,backache, tired.. cramps stopped the day AF was due (friday) so now I'm confused as ever being late is going to throw my cycle off 😢 and btw would this test be faulty because of the gap in the side every time I am about to take a test it's either faulty or has something wrong with it is this a sign that maybe is not my timing to conceive!!
