The Chinese pregnancy calendar was right for both my pregnancies and for my friends too
I carried extremely high with my boy, and his heart rate was always 140.
apparently i heard if you hold a necklace over your tummy depending on the direction it moves will determine the sex butter i don't know whether its true or not x
I carried high with both of my boys, and low with my girl. My girls heart rate was always in the 160s and my boys were 140-150. I had bad acne with my daughter, and gained weight everywhere. Hope this helps! Look up the Chinese gender chart, it was accurate with all 3 of mine!!
