what do you think?!

I haven't had a period in 3 months (never late ever) and I got 2 faint hpt's in May. Ever since, I've been getting negative ones at the doctor's (both urine and blood). My GYN even drew blood and tested for hormones that could be out of whack, finding normal results. Now, she wants to induce a period, but I still feel super pregnant - not to mention, my stomach is still growing. I just FEEL pregnant; it's like I just know I am (even though this is also making me feel crazy 🤦🏾‍♀️).
I told her I'd induce the period if I see an empty uterus on an ultrasound, but only after that.
Has anyone found they were actually pregnant even after negative qualitative/quantitive HCG tests?
