If you give birth vaginally, your vagina will probably remain a little larger than it was before. Right after delivery, the vagina will be stretched open and may be swollen and bruised. Over the next few days, any swelling you might have starts to go down, and your vagina begins to regain muscle tone. In the next few weeks, it will gradually get smaller. Doing Kegel exercises regularly helps restore muscle tone.
Start with an empty bladder. Imagine that you're trying to stop yourself from passing gas and trying to stop the flow of urine midstream at the same time. The feeling is one of "squeeze and lift" – a closing and drawing up of the front and back passages.
Make sure that you're squeezing and lifting without pulling in your tummy, squeezing your legs together, tightening your buttocks, or holding your breath. In other words, only your pelvic floor muscles should be working.
Though you may have trouble isolating these muscles at first, it gets easier with practice. It might help to place a hand on your belly while you're doing your Kegels to make sure that it stays relaxed.
If you haven't been doing Kegels, start by holding each contraction for a few seconds before releasing, and relax for a few seconds after each one. As your muscles get stronger, you'll want to work up to holding each Kegel for ten seconds, then relaxing for ten seconds after each one. If you're suffering from urinary incontinence, try to hold a Kegel while you sneeze, cough, or lift something. You may find that it helps keep you from leaking.
