Nervous 😫😫

Ok sooooooo I am 4days late. I want to take a test but I don't want that BFN. I try not to think of it but I'm kind of excited anxious. I'm thinking maybe my cycle is just changing because I only had sex once around Ovulation, which was the first day.  I really don't have any symptoms but backache,couple cramps, and headache, insomnia and fatigue. I don't wanna get my hopes up and then be let down😔😔 Because I suffer from POS and sometimes forget to take my Metaformin(however you spell it) lol
