Wahh./: feels like everyone is getting their little miracles.. But me.

I am trying for my first with my fiancé, and we have been trying for at least 5 months now. Today is my first fertile day, according to glow. I have always used the period diary app but not been successful when it came to ovulation, not that I expected it to because my period is not always the same amount of days each cycle.  I really don't want to go all out and start tracking my temps and ovulation tests but (yes, I know. Some ladies have waited years for their BFP, so 4 months isn't a lot) I just seem to feel so, frustrated. So this month instead of just having sex here and there and not thinking about trying and just having fun we are BD every other day, sometimes twice. What are the chances of maybe getting my BFP?
