Anyone get preg one their first try?

I got my nexplanon taken out late Jan., had my first cycle Feb 9th.

I had spotting maybe 4-5 days ago and am supposed to see AF today but nothing yet. Iā€™m cramping so feel like I should be starting soon but idk?

Did anyone get preg on the first try or is AF just playing games with me? šŸ˜ž
