21 weeks-husband says I feel dilated

Two weeks ago, my husband politely let me know that I felt a little dialated, I tried not to over react though it did bother me so I began researching and doing daily kegals as many instructed. My husband was away for work for a little over a week, then last night there were issues with neither of us getting the end result that we were seeking. Again, polite as he could be, he told me I might need to see my OB and make sure everything is okay since I'm only 21 weeks. I feel perfectly fine, and just had a ultrasound last week so no issues with the baby though I am seeking advice. 
Please help!
