Oh aunt flow ... u are funny 🤔

My body is playing games with me lol i have pcos , i was on cd 74 & voila ! I just got my period today .... 3 days before im supposed to meet with a fertility specialist lol so im wondering since i will be on cd 4 when i go to my appointment im wondering if they will be able to do any testing this month or would i have to wait until my next cycle? Im just hoping this speeds up the process a tiny bit since i dont have to wait for my period to come or take provera since it came on its own . Any input would be great !
