Clear period

With this birth control (aubra) for a couple days before my period i have all the symptoms of my period (my vag & whole area down there is sore & tender & it feels wet) but it's all clear liquid & not even that much.. I wonder if it's just the mucus since my periods are super super light now but more mucusy.. But ugh i hate feeling on my period but theres no blood so im paranoid when i go out 🙄😒😩
