Been trying for #2 for 4 months and feeling down

My husband and I have been trying for baby number 2 for 5 months, I'm 27 he's 30, were both healthy non smokers I could loose about 25 lbs I've been exercising with my son almost everyday. I'm just feeling down reading things on google about blockage in tubes leading to egg. And  cysts and polyps!  I got preg first try with our son... Just feeling down about it.
