So, you’re in your first trimester of pregnancy (yay!).

Your body might feel different, but it doesn’t yet appear to be different. Instead of looking like there’s a baby in there, it really just looks like you ate a big burrito.

People are puzzled: pregnant or just pudgy? (Not that it’s any of their business.)

In fact, aside from the “morning” sickness, sore breasts and hormonal hurricanes, let’s just call it as we see it, Cupcake — you don’t even look pregnant to yourself.

You may still wear the same clothes and still sleep on your belly. You may be the mama who sheepishly says “I’m 10 weeks along” instead of the one who beams while announcing  that she’s practically waddling into the delivery room. You may even still be taking your regular yoga class… but that doesn’t mean you don’t need to modify it a bit.

It’s important to remember that even if you don’t look or feel pregnant, you are. Your body, and your baby’s body, needs a little extra TLC.

There are a number of yoga tricks for each trimester. When I was teaching prenatal yoga to private clients, my fave for the first 12 weeks was the “bra strap rule.”

The bra strap rule is a super-simply, highly-effective guideline for torso twisting during pregnancy.

In non-pregnant yoga practice, deep twists are often encouraged to “wring out” the spine, “squeeze” the organs and create space in the trunk and torso.

In prenatal yoga practice, though, such movement can stress the uterus where your baby is growing (which is why some prenatal yoga teachers eliminate twisting entirely).

Problem is, many mamas crave twisting to help alleviate the aching back-collapsed chest-tired neck-itis that ails.

The bra strap rule is your middle-ground solution to prenatal spinal rotation, and it has three parts:

* Instead of playing a full-on game of twister with yourself, simply keep your baby facing the same direction as your pelvis.
* Then, gently twist your chest, shoulders and neck — the part of the torso above the bra strap line — for a subtle, but noticeable, opening of your upper body. Slowly build up to 25% of your normal rotation.
* As always, once you’re there, be sure to breathe deeply, consciously, deliciously.

Ahhhhhhhhhhhh, right?

This rule isn’t just for “yoga mamas,” either — any pregnant mom can use this for twisty motions, like sitting in the driver’s seat and turning to reach something (or, ahem, someone) in the backseat.

Of course, these are just a few guidelines to help you get in to a habit that encourages optimal health.

If you’re in your first trimester and you have already been a little bendy with your belly, no freak out required — simply start being mindful about moving more carefully. This is especially true early on, as your little one is really, really, REALLY little and not likely to be affected by your normal movements.

As your prenatal practice progresses and your baby bump starts to grow right under your nose, you’re more likely to remember to turn without totally twisting your uterus.

Until then, let the bra strap rule be your reminder that your oven’s turned on, baking and requires a watchful eye.
