Possibly pregnant

Raquel • Married.Mom 👦🏻 10/15/14. 👧🏻 2/12/19. 👧🏻 12/21/20 trying for baby #4

I got my nexplanon out 2 weeks ago had sex 4 days after then again 2 days later. I’ve been nauseous since yesterday and breasts are feeling sore. Has this happened to anyone else and ended up becoming pregnant?
