I had high fertility results from day 9 of my cycle. had sex on the 11th. on the 13th, i had peak fertility and much cervical mucus. morning of the 14th day, was still at peak fertility, little mucus. evening 14th, neg opk test. should i be hopeful?

Do something else: Do something else and not think about hope at all. Normal, fertile couples who are having lots of sex should be able to get pregnant within 9 months of trying. Many get pregnant within 3-4 months, but a couple isn't in trouble unless they've been having lots of sex for 9-10 months and still no pregnancy. What will be, will be... meaning not overthinking things is a good way to live.
