Frustrated!!

I am 33 and a super big health fanatic. I have been 100% healthy my entire life. My husband who is 14 years older and I have been trying since February for a baby. Just this month I have some fatigue and bloating. This is frustrating the heck out of me because I am super tired in the mornings. I have read that I am ovulating but according to this app my week was last week and I took a pregnancy test and it was negative again. Has anyone dealt with this before?
