I'm losing hope for my BFP...

jj
I have irregular periods and this is my first month tracking with glow- so I'm not sure how accurate my chart is. I have PCOS. I feel so pregnant. I am nauseas, have food cravings and aversions, am very bloated, was having diarrhea and am now constipated, have sore nipples, cramp after orgasms, have little to no CM (unlike usual), and have an overall feeling that I'm pregnant. I just feel so different. I am 5DPO, and took a test 1DPO, 3DPO, and now 5DPO. I know it's very early but I am high risk so I need to know as soon as possible... All tests were BFN. They are dollar store tests and have the 25 sensitivity. My fiance and I are so excited and I just need to know asap... I know women get positives before their periods are due, and I hopefully will too. What should I do?
