I need some advice..? (Might be tmi..)

Kati • 22! 😍 Loving life. ~ 💕
I got my period last month on Feb. 15th. It lasted 4 days (normal for me) but last month I was exactly 5 days late. & my period wasn't 'normal.' My second days are worst, but last month I barely had any blood clots at all during those 4 days. Maybe a couple at most.. This month, AF was due 3/15 & I'm currently 3 days late. My plan was to call my gynoclogist after AF this month bc im also due for my annual check up.. I don't want to scare myself but I've been TTC for 9 months. It was just really weird and the 1st time that's ever happened to me. Any advice or suggestions?
