Not actively ttc, but if it happens it's ok. I've decided not to drink from when I start my fertile window until I get my period every month, so that's about 2.5 weeks. I figured if I drink on my period or before my fertile window it can't affect a possible future pregnancy. Is there some truth to my theory, or is it complete nonsense?

Edit: I've read that drinking during tww increases chances of chemical pregnancy etc
