Super light period? PLEASE HELP!

Joana • I`m Jo, I`m 19, & I ❤ Video Games!

So I'm on the pill, and I'm sexually active. This will be my first period since I've been off the implant. I've only had 3 periods while I was on that.

I've taken my third inactive pill today and all I'm seeing in what should be period is light mucus mixed with blood. I don't even need to wear a pad because it's so light. And it's bothering me because pads irritate my skin.

Is this my period? Is this normal? I normally have a moderately average flow. So this is new to me.
