Hello. I'm all a bit new to this. I am 1 day late with my AF... 15 DPO. I have done a couple of tests because I'm very impatient and a line appeared on a cheap strip test. I have read that this could be an evap line. I felt sick, have had headaches, felt very bloated and I've also has very very light spotting for a few days last week. But I haven't had any other symptoms and now I'm having cramps which feel like period cramps but I don't normally get them. When's the best time to test? I'm really praying for my BFP
