Nexaplanon issue

So I got my nexplanon inserted on April 27th of this year so next month on may 14-18 got my period and then stopped and then I think I got like spotting on the 22nd and then my period was completely gone till this day today but I be getting random so I’m like ok yes no period I don’t gota deal with period but now recently I get like period like cramps so I’m ok darn I guess I will get me period but it goes sometimes so so intense but then it goes away so I’m I confuse is this normal or what do I take a test ?
