Prenatal yoga for hips & back

I'm pregnant (cleared to exercise) and want a 25-minute prenatal yoga session for tight hips, lower-back relief and calm breathing. No deep/closed twists, no lying flat on my back, no deep backbends, and no breath-holding. Warm-up (5 min): seated or all-fours diaphragmatic breathing, then 8 slow cat-cows. Main flow (15 min), holding each 20-30 sec, breathing the whole time: supported wide-knee child's pose, all-fours hip circles each direction, low lunge with hands on a chair (each side), supported standing forward fold with hands on a chair, garland/supported deep squat holding a chair, seated side bend each side, gentle open (not deep) seated twist looking over the shoulder each side. Cool-down (5 min): side-lying rest with a pillow between the knees and slow breathing. Give me breathing cues, modifications as my belly grows, and a reminder to come out of any pose that feels strained.
