Did any one only BD the day before you ovulated and still get your BFP?

I miscarried in May, and I still haven’t gotten my period.

We BD on Sunday, but last night I had the most EWCM I have ever had. But my husband had a hard time.

Do you think Sunday could have been enough? Should we try and do it again tonight?

I’m really feeling discouraged, I could really use some positive vibes.
