Feeling guilty...

We had an ultrasound done at 15w3d and the tech was sure it was a boy but my over analytical mind can not stop wondering what if she is wrong? So I finally convinced my husband to let us go get another ultrasound at 17w2d next week but now I feel so guilty because all that matters is that we have a healthy baby. So why am I dwelling on this so much?!?
