So confused

My husband and I decided to start trying for baby #2. We weren’t able to BD as much as I would have liked to....obviously. I know it only takes once so we’ll see! I’m pretty sure I ovulated yesterday based on how bad I was cramping. I also took OPKs the last 3 days. I know they are positive but they just keep getting darker so I don’t know. I’m sure it won’t happen this month but you never know I guess!
