Sooo lost!

Morgan
I'm on CD 46 still no AF
​All of my tests are BFN.
​I was on the birth control that I would only get AF once every three months. I got off of that two months ago. I've been super dizzy, sore breasts, I took work off the other day and slept for 10 hours! I was spotting last week a little bit. Everyone around me is convinced that I'm pregnant. I just can't decide if I should go to the doctor to get my blood tested, or just wait it out because my body is still adjusting to life without birth control!?!
