Nexplanon.. 2 periods?

So i been tracking my periods on 2 apps.. my other app was easier to show everything at once. So may 11th 2020 i got on nexplanon. The first 6 months i had no periods. Couple months after i got them once a month like i normally would. Then in 2022 i started getting them twice a month.. its gotten to the point were if i feel 1 little cramp im putting a pad on. There not predictable.. i know when i called my obgyn she told me to document them then make an appointment. But i havent had time or the money to actually see her. Is this something i should bring back up to her an see what i should do. Its just tiring having 2 periods a month..
