Please give me hope I'm depressed

Has anyone ever got their bfp, using preseed and soft cups and had sex on their fertility days up until ovulation day and missed it but had sex after ovulation day?? I feel like I missed my window.... I want a baby so so bad and I feel I failed. I haven't been ttc long but there's more to my story in my past.... I don't want a bfn...if I get one I feel like I'm just going to get back on bc and use condoms, sex drive will eventually disappear. I'm hopeless....anyone??
