BFN - also confirmed low sperm count

Melissa • Just tracking my period!
Oddly, my husband did a semen analysis the week before I found out I was 4 weeks pregnant. Dr. called and said he had 11  million count and 46 percent motility.
​This would have freaked me out if -- wait, I still freaked out!! I keep thinking I'm faking it or something. Two tests and now 5 weeks and 2 days. 
​Any words of encouragement to stop this insanity?
