Soooooo confused

hi everyone so I’m new to the site and get for baby no3

i had my coil removed in February and we used protection up until June so I could get my cycles regulated. They all been 32 days bar one that was 28.

weve been very active ttc but that’s no different to how’s we usually are. 

This month I really though we were in for a chance and out of no where I started bleeding 5 days early?! Very heavy but it only lasted 2 days? 

Im so confused with what’s going on don’t know if anyone has been through similar?

i know we’ve only been trying for 2 months and it takes time but I’m confused at why my cycles have become irregular since ttc
