ttc such a struggle

I'm so frustrated to tears, I've been trying to get pregnant with my husband after we miscarried in June. I missed my period and have had really sore boobs and nauseated and throwing up with all those little symptoms... I finally took a test today to just get bfn. I'm going to wait a week to take another test if I don't get my period. if I do get it I'll wait till after it's finished to start my conception vitamins
