Pregnancy symptoms after implant removal

I’ve been having unprotected sex since the 8th May since having my implant removed on the 8th, I didn’t have any periods with the implant and still haven’t got one yet. This past two weeks i’ve been experiencing sore boobs-it’s not a horrendous pain but still really uncomfortable, mainly on the sides, and my areole slightly bigger too. Really bad headaches focused on forehead, light cramping and mild clear discharge

I don’t know if this is PMS as haven’t had a period for 3 years! Or I’m pregnant. I will test! Just unsure when to do it aswell due to no period! Any advice? Has anyone had similar symptoms for pregnancy?
