If you are they are testing u to early, wait a few more days and test yourself. I have a friend who has positive tests multiple ones and different brands all giving her BFP, but her blood work is negative, so don't give up hope yet.
I get my 2nd blood draw tomorrow morning. Really trying to stay positive. The only pregnancy type symptoms I might have are insomnia, hot flashes, and bloating. But those could all be due to meds also.
It's probably to earlier to test anyways. My first beta was 11p5dt. It should raise by you next visit. Good luck!
