I’m trying to have a baby 😩😭

Me and my bf have been trying all year and still no baby 😭I’m keeping up with my periods and when I ovulate in here ,we have a “sex box”😂 so I know the exact days I’m having sex so I don’t always add it to my calendar , I notice a change these last 3 months my period has came on a week earlier then normal every month ,dk what it means but hopefully good things. I’m 24 and I’m so anxious and really want a baby please help 😭😭😭
