I tried for 9 years and it finally happened. I figured out some health issues and fixed it and all of a sudden bam pregnant 5 months later. It can take a lot of time. You are only fertile when egg is the right spot for 12-24 hours

Yes we both do and yes we are stressed and maybe trying to hard I don't know

Have u seen what was the causes,sperms,stress,trying too hard etc.

Talk to your doc
