BFN AGAIN

So disappointed again a bfn been trying to get pregnant forever after my miscarriage in July! That pregnancy was unexpected ita true when they say “when you don’t expect things to happen it happens and when you do expect it to happen it never happens!” Just ordered OPKS for the first time hopefully this will be helpful. I have regular periods and have done pelvic examination bloodwork they did saw a small cyst on my right ovary it was on my right one few months ago something new to me never had this before could this be the reason for us not to conceive? Please some answers girls..
