Negative PT/ TTC @34

Just looking to see how long it took others to get pregnant. Never been on birth control before and began trying this month. My husband likes to have 1-2 sessions a day, so I thought for sure we would conceive. My period is due to come in a few days and no positive tests. I didn’t think it would be hard to conceive, so I’m bummed because I expected it to happen immediately. How long did it take you to conceive? And how long before a PT was positive?
