What were your symptoms?

I am 7dpo and have been cramping since 4dpo. I have headaches on and off, nausea, dizzy spells, always hungry or craving something, nipples are really sensitive and I’m more tired than usual. I’m TTC Baby#2..Baby#1 is 13 months old, my last period was in February. I track my CM and use OPKs to track ovulation. I tested 3 days ago and it was negative with a clearblue digital. What should I do? What were some of y’alls symptoms before your BFP?
