Re: Should your cervix be perfectly circular....
Pretty sure mine's irregular, it also varies hugely according to where I am in my cycle.
Be careful about checking yourself, it's one of my bad panic habits and I tend to get careless, make myself bleed and then spiral.
May I ask about your wacky periods? In peri and very much struggling with what's normal right now.
Edit: also nabothian cysts are a thing, they're harmless and feel like smooth round bumps.
