Frustrated! My doctor brushes me off!

Laycee
I had multiple positive pregnancy tests and they all gradually got darker. I was 10 DPO when I decided to get blood work, since I thought I had my BFP.  The doctor called and said it was negitive. She said it's probably stress causing my period to be late... my period is late by a week, I am nauseous at food (which makes me sad...), my breasts are so sore, my face looks like I'm a 13 year old with all these breakouts, and last but not least I have the weirdest dull feeling cramps. Ever since I started my period when I was 12 years old I would wake up with a huge headache the morning before I start my period. This month I woke up with a huge headache thinking my period was about to start since I was two days late already and it still has not 😒 I am so frustrated that my doctor just brushes me off. So the blood test says negitive, I still want to know what the hell is making me test positive on every HPT I take. Why am I so late and why have I been having dull cramps but no period 😭
Sorry for the long post, I also needed to rant.
