I think I’m pregnant but the test says no


I have never wrote in here before but I have questions that I want answered. I was in the pill for almost a year and then I got off in January this year, my periods started as regular after I got off the pill and then went back to been irregular after a couple of months ( before I was on the pill I had irregular periods). But this month feels different I’m gettin all sorts of symptoms like sore boobs, nausea, exhaustion, wanting to sleep all the time weird sense of smell and more I took a first response test yesterday and about a hour ago and they both have come up negative but I still think that I could be pregnant. What are your thoughts.
