It does sound like the baby is pretty low, if this is your first they can engage very early on...but for the others, it should not really hurt to clean there.  Does it burn or sting?  Is it red?  If so tell your doc and see, it could be irritation from clothing to an infection.  As it's more engored from all those hormones and extra fluid....Certainly give your doc a call to see what they say....Good luck and it's almost over!!!

Ah yes I remember the feeling well. You will get pressure in your pelvic area as the baby sits lower properly engaging his her head. Sleeping with the pillow is a great idea and so is the bathing to relieve the weight on your ligaments. Unfortunately sorry to say that feeling didn't go until the baby was born. But hang in there it is all worth it. don't sit for long periods of time as it adds pressure, try and lie down and walk in short periods. Good luck with it and I hope you can get some relief.
