Jewish Pregnancy Customs

[Heaven]

Ok, I'll post the first thread (I'm not Jewish tho, just curious). I read this recently:

The following are some other pregnancy and birth related customs which are practiced by various Jewish communities:

• Some have the custom to keep a pregnancy secret from friends and acquaintances until the onset of the fifth month, unless it becomes plainly apparent... This restriction does not include close family members.
• Some have the custom for the husband to open the synagogue ark before the Torah reading during the last month of pregnancy. The Zohar says, "When the congregation takes out the Torah Scroll, the Heavenly Gates of Mercy are opened, and G‑d's love is aroused." The husband opening the Gates of Heaven hopefully elicits G‑d's merciful blessing that the birth be easy and without complications.
• In certain communities it is customary for the pregnant woman to immerse in a mikvah sometime during the ninth month of pregnancy. Speak to your local rebbetzin or "mikvah lady" regarding planning and preparations. It is advisable to consult with your OB/GYN before going to the mikvah.
• During the term of pregnancy, both mother and father should increase their recitation of Psalms.
  Before going to bed, it is customary for the husband to recite Psalm 20. When finishing, he should repeat the second verse of the Psalm.
• The home's mezuzahs should be inspected by a scribe during the months of pregnancy. If one does not have mezuzahs on all the home's doorways, now is a great time to purchase new mezuzahs.
• A pregnant woman should endeavor to be exposed to spiritual and holy sights and sounds. To this end, whenever possible she should avoid gazing at non-kosher animals (trips to the zoo can wait until after birth...) and listening to gossip, slander, or other unsavory talk.
• In many communities, pregnant woman do not visit cemeteries. Perhaps this is to avoid settings which can lead to negative emotions.
• There is an ancient custom for the pregnant woman to sew a sash (know as the gartel or wimple) for a Torah scroll. If the newborn is a son, the sash is used on the Torah from which he receives his Bar Mitzvah aliyah, and then once again the aliyah on the Shabbat before his wedding.
• It is customary to have a copy of Psalm 121 on hand during birth.
• If possible, during the final stages of labor and delivery, the husband should recite these Psalms: 1, 2, 3, 4, 20, 21, 22, 23, 24, 33, 47, 72, 86, 90, 91, 92, 93, 104, 112, and 113 through 150.

Do jewish people still do these things? And are there any others? What is the reason behind them?
Imagine reciting all those psalms during the final stages of labour. I think I might tell my husband to shut up if he started doing that!!
Anyway, I was just curious about pregnancy customs in different religions.
Do these things still apply to Jewish women today, or is this just an unreliable website I was reading?? lol.
