Low Blood Sugar

Ashley • I'm 26 years old and have a 4 year old son named Keegan, with my husband Todd. We are expecting baby #2 on March 18, 16.
I just had an episode where I got sweaty and dizzy and got my grandma's suger test and tested my sugar and it was 52. She told me that 90-100 was normal. Has anyone else experienced this and what is the best result?
