I'm still trying to get this down.

Hi I'm new to the community. This is my first post :) My fiance and I have been TTC for a year now with no luck. I feel like I've read everything and done everything I can. I'm constantly checking my CF and CP. My ovulation always seems to be irregular. According to the app I should've ovulated on day 13. Today is day 16, I went to check my CP and got some EWCM. The second we were both home about 5 hrs later we BDed and I kept my hips elevated for 30 mins afterwards. I just really want to get there so bad and I'm hoping this month is the month but I'm just feeling kind of helpless as a woman right now. I have kissing ovaries and I'm fearful that could be what is making this so difficult although my doctor said it shouldn't mess with my fertility. I just don't understand why my first just happened and now that I'm trying and trying it's just not happening. I'm just feeling really defeated.
