HELP! BFN but still pregnant?!?!?! 🤷🏻‍♀️

wv
Has anyone ever gotten negative urine and blood tests and still been pregnant?! I've had every textbook sign and symptom except sore breasts. I'm currently 12 days late with AF. I've taken several HPTs over the last 2 weeks and all were BFN. 😩 I had a GYN appt on the 9th and she checked my cervix. She said my cervix was high and possibly enlarged. She said she thought I was pregnant and did a qualitative HCG which came back negative. She ordered an ultrasound which I go to on the 15th. In the meantime I am going crazy. I don't know if I should be happy and excited that I may still be pregnant or if something is wrong down there 😟.
