Thanks for your query.
From the history that you have provided it seems that the baby has descended into the pelvis recently. From this time onwards pregnant women may feel some pressure while walking and sitting. You may try to lie down on your side to relieve the pressure. Most deliveries during first pregnancy
happen in the two weeks preceding the due date. Thus you may need to keep a bag ready, in case you have to rush to the hospital. Best strategy is to relax and wait for things to happen naturally.
Hope I addressed your concerns.
