TTC ?

i got told i had a ovarian cyst a few weeks ago and that it would dissolve on its own . I have irregular periods & I always have intercourse on my fertile days . i check my CP here & there and im not a pro or anything at it but i could never seem to catch it open during the days im fertile and Oing . is it harder to get pregnant because i have a cyst ? iv been having a hard time trying to get pregnant .
