Help!! 😩

Ana

I'm so confused, my period is 2 months late & I have been feeling nauseous but not to the point where I actually throw up, serious headaches, very moody/emotional & also very tired. I took 2 tests about 3 weeks ago & one came back negative & the other one was a very faint positive. I also went to the doctor yesterday & they made me take a urine test & that came back negative as well! 😩 I'm getting frustrated, I just want to know what's going on with my body. Could I still be pregnant?
