Ovulating late

Bryanna

For some reason last month I ovulated late and I was suppose to ovulate today but didn’t last time I got my period at 13dpo.. I do smoke marijuana & I feel like maybe that’s doing it but not sure. I’ve been trying for some time and this month is my first month using pre seed but it seems like it’ll never happen like everyone around me is getting pregnant and I’m still seeing that one little negative line🙁.
