Nikitaji, during pregnancy each trimester has different sets of asanas. Definitely not these poses! Shoulder rolls, neck circles are ok, as also simple joint-energy releasing poses. However, it would not be advisable to try anything new, reading it over the net while pregnant! Instead joining a prenatal yoga class would be a sensible option because the teacher can guage and design your sadhana based on your previous level of activity. That is crucial also. If you are from Mumbai, I think there are some prenatal classes conducted in Bandra. Hope this answers your query:)
