Good Vibes Needed Testing in the Morning

Me and my husband have been trying for 2 years on and off but have been seriously trying for the last 6 months I recently lost about 30lbs and this month had brown discharge about 1 week after my period ended it was light and lasted for a good 5 days.. Tomorrow would be when my AF is due and this past week have been feeling tired nausea back ache and light cramping on my right side. I can't wait to test but I am also scared bc I will be really disappointed if it is negative.
