Wazifa for safe pregnancy

Q: I had a miscarriage in April due to no baby heartbeat. Now I conceived again Alhumdulilah but yesterday I went for ultrasound and they said that there is a baby without foetal pole and they said that I should come back in a week to check the baby's heartbeat again. Please suggest any dua which I can recite and Allah give a heartbeat to my baby and I will be safe from miscarriage. 

Men and women's clothing

Q: Why are women said to wear burkha but men aren't. And how should a Muslim man dress? And like if I like a sweat shirt am I allowed to wear because the sweat shirt(not body tight) can look good and still attract the opposite gender. So is that permissible in Islam, to wear nice clothing?
