Am I going crazy?

I am at a loss!!! I have now missed 2 periods... I took 2 tests a week after I was expecting my last period - both were negative. Went to the doctor about 2.5 weeks later and got another urine test done - negative. I felt completely fine this whole time, and didn’t think I was pregnant, I just wanted my cycle back on track. Now, this past week I have been feeling all of the symptoms of pregnancy!! Is it possible to have that many false negatives after that amount of time??

I do plan on going to the doctor to get blood work done next week. But last time I went to the doctor, that’s what I asked for (a blood test) and they gave me a urine test and just brushed me off. So I thought I was not pregnant and everything would go back to normal soon, but like I said, now I’m FEELING pregnant.
