Looking for some advice

Hi ladies, I'm 33 and have been trying to get pregnant with my husband for 8 months. We haven't been lucky thus far. I was wondering if any of you have altered your lifestyle to get pregnant?

I travel at least once a month for work and work in a sales based role (so can be stressful). I exercise to regulate myself (strength & hit). There are times I do put pressure on myself for not getting pregnant and wonder if it's due to my lifestyle? We did tests recently to see if there were any issues and they've come back normal. I was wondering if anyone else has felt this way. Would love to hear from you.
