Please help:/

Based on my last period I would be 6 weeks,

Well... I had negatives all the way up until 9 days late, I went in today when I would be exactly 6 weeks and the nurse said my pregnancy test was very very faint and wanted to do a transvaginal to see if she could see how far along I am.

Well she put the probe in and said there was nothing. No ges sack, no yolk nothing... im so worried. She took blood and said it could still be very very early, I can’t help but be so worried that it’s ectopic or what!

Please send any advice or experiences.
