Hello, I would be happy to help you with your question.
Hopefully since you posted this question you have gotten checked out. But given this being your 5th pregnancy
, 5cm dilation, and painful pressure in your vagina, you are at HIGH risk of an unplanned delivery at home. You need to be admitted and observed in a setting that is safer should you go into labor or rupture your bag of water. Simply tell your doctor that you are no longer comfortable staying at home and would like to be more closely observed while this pain is present.
I hope that this helps you. Please use the PREMIUM SERVICE if you would like a more detailed and timely answer.
