Pantang - before miscarriage

Hi ladies recently I lost my baby. I have engaged someone to do my post miscarriage massage. She gave me few tips and asked if I follow and I wanna ask u ladies got do the same and your believes? I'm not very religious but I do pray and respect every religion. She asked if I kept sharp objects with me all the time which was a no. She advise to keep like a knife near window where I sleep which I didn't do also. I had bad dreams like I know I'm going to lose my baby. Any of you experience the same before miscarrying? I only can feel sad because honestly idk wht was the reason and why I lost my child but I regret for not taking more precautionary measures be it a blind believe or not rather be safe than sorry. It's like not a joke when elderly people advise sometimes can be funny bt mostly for good. Please share ladies!
