Heavy Flow
During heaviest menstrual flow, you should not do yoga poses. Doing this could cause heavier bleeding because of the pressure the poses exert on internal organs. Instead focus on breathing and meditation on those days.
High Blood Pressure
If you suffer from high blood pressure, you should NOT do inverted postures.
These postures increase the bloodflow and can cause serious problems.
Alternatives
There are many variations to most postures. If you experience pain or discomfort in any posture, remember to stop immediately. Don¡¯t force anything; you can find an alternative.
Waiting Time
Yoga exercises exert pressure on the internal organs. So be sure not to eat before practice. If you¡¯ve eaten a meal, wait at least two hours. If you¡¯ve eaten a snack, wait 30 minutes to one hour.
Poses You Should NOT Do
While yoga can help you adjust to the physical changes you undergo during your pregnancy, there are several poses that you should NOT do.
Mainly these are inverted postures and those that place your weight on your abdomen.
Do NOT do: Bow, Cobra (or the seventh part of the Sun Salutation),Plow, Peacock, Shoulderstand, and Headstand.
Avoiding Knee Injury
To avoid knee injury when doing yoga, be sure to keep the knees straight (especially in standing poses). The knees should be forward in line with the ankle and foot. Do NOT let them push or twist inward or outward.
