Helpppp!!!

Im freaking out!! So i had my implant removed early may (i had nexplanon in for 6 years) i am 1 week post ovulation (i think, i went off of my last cycle in 2019) and now im experiencing abdominal cramps (worse in the morning, mild the rest), nausea, vomiting, lightheadedness, dizziness, and the sore tatas. I know it says I'm due to start next week, but is there any chance this could be preggo related or is it all in my head? If its not when should i test?? Could use allll the baby dust right now!
