Do you believe in certain Filipino folklores relating to giving birth? I.e. "suob", "hilot", "binat"

Same here. After giving birth, my O.B. gave me a go signal to take a bath. However my in-law told me about "binat". After 1 week I experienced severe back pain and difficulty breathing. My in-law confirmed that it was "binat" and immediately scheduled me for "hilot" but when I consulted the doctors (OB & ER doctor), they told me that my body is just adjusting since I'm also breastfeeding. So I'm not sure if I should be scared that I did not listen to my in-law. Some say that there are people who died because of "binat".
