Feeling pregnant after removal

Abby

I had my nexplanon removed 3 days ago and have BD every day since ( got off my period the day of removal) today I woke up nauseous, sore breast, cramps, watery discharge. Took a test ( had one at home) just to see and its negative. Is it normal to have all.these symptoms after removal? We really want our 3rd baby and hope to get pregnant soon!
