I just need some help.

So for the past yr..my now husband nd myself have been TTC. I just recently started taking prenatals. (I heard they help) I plan my special night's. (My husband has a low sex drive nd convincing him to have sex is a job so we plan it) I've rencently had a miscarrige (3weeks). We are desperate. We will try anything. Anyone has any advice on how to help I would greatly accept. I am stressed out like crazy right now over this.
