Cycle days?

Wendy🌻 • Mommy to 4 sweet babies. 2 beautiful girls and 2 handsome boys. Baby #5 is a GIRL and due in June!!
So I'm just curious.. Anyone here have 30 days in your average cycle? 
My period has been 6-7 days Long and 'proof tracker' says I have a 30 day cycle. 
With my first two children I had a 28 day cycle, does 30 days mean it could be harder to concieve? 
Sorry if this is a dumb question!
