Nikki • I crave adventures. 🗺🌏
So I've been on the pill for about 6 months now and I usually have my period 3-4 days into the placebo pills, but this month I thought it started cause I saw pinkish discharge around 3-4 days and it stop that same day. I already started my new pack of pills and technically didn't get my period yet, what is wrong ?
