Sperm morphology

Janelle • Thrilled to finally be expecting #2 after a lot of trying and an early MC. High risk all around but staying positive!
I just got the SA results and everything came back good except 4% normal on the morphology. Has anyone else experienced this? Any idea on causes or treatments? The count was 10x normal  though so my OB said it's not an emergency just yet.
 I'm still freaking out a bit since they want me to make appts with a fertility specialist and a urologist. On top of everything, DH is in Mexico celebrating my little brothers bachelor party and I don't want to ruin his trip with the news.
​Any advice is much appreciated!!
