disappointed

Me and my husband have been trying to get pregnant. We have two kids already and I've been trying to have sex with him at least 2 times during ovulation. What I'm nervous of is my brith control messed up my schedule and glow cant tell me when it really is.. how do figure it out? Yeah yeah, I can't remember back to 8th grade health! Also adding.. nobody knows, so I can't ask anyone but you ladies. Which is what's driving me crazy. I keep dreaming I'm pregnant with a girl and I can feel the baby movement in my dreams like they're real movements! Ughhh... help me please? :(
