I would not go off of symptoms, as they are not reliable at all. The same symptoms could just mean that your period is coming or that you are stressed. Dollar store tests are reliable, so if you took it at the correct time, then they should be accurate. Good luck
Even though the dollar store tests are cheap in price,they really give an accurate result. I used them on 2 prior pregnancys and received a + result and I really was pregnant. With that being said, you may still be pregnant but perhaps too early. You can try retesting in a couple days with first morning urine. I wouldn't put too much stock in the symptoms though. With that amount of symptoms,you shld deffinately have tested positive already. Best of luck! Hope you get the results you want next time.
i also have bad heartburn all the time and during the night i have hot flashes and i start sweating.
