Has this happened to you?

I have missed 3 months of my period. I wasn’t sexually active nor am I on the pill. Made a appointment to see a obgyn doctor to get checked last month. But I had to reschedule for this month because I was starting to bleed a little. Didn’t last long though. Now fast forward to today where it’s the day before my rescheduled appointment and now my damn period wants to start acting normal as if it didn’t skip 3 months with a light period last month. So frustrating... 🤦🏽‍♀️
