Should i worry

Hey all.

I'm am pregnant with baby #1, or rather i think i am. I have taken 4 hpt and got the same bfp but i have never gone for a blood test for confirmation.

Hubby and i decided to wait until week 11 for the first us. All my symptoms have disappeared so now im worried thats it's all been in my head.

Did any of you have the same feeling of worry? Are there any moms who also waited over 4 weeks for their rock hard confirmation that they had a little jellybean growing inside them?
