HELPPP AM I PREGNANT W/ A FALSE NEGATIVE?

For the past week and a half, call it two weeks I've been VERY bloated, having headaches, cramping, Implantation Bleeding or (could it have been a UTI?) Fatigue, Nausea (w/o vomit, usually at night) Frequent Urination, Tender nipples, & etc. AF is due is 3 days according to Glow but on my Flo app it's due in 2 days. I'm 11dpo and had sex every day of my fertile window except 1 day. 3 Negative pregnancy test. Is there a chance that I am pregnant? Should I re-test in a couple of days?
