It's never a bad thing to have low cholesterol. Mine is still low but, I think, reasonable. Last testing, 149 (non-fasting). It originally was around 120-125. Look at it this way...you'll probably never have to worry about heart disease! Be more concerned with raising HDL......mine was in the 20's and now is just under 60.
Good luck and congratulations with the baby!
Cholesterol that is too low poses many health risks including, connective tissue disorders, chronic inflammation, cancer,. mental illness, depression, anxiety, and mortality. Not to mention that it decreases your ability to absorb fat-soluble vitamins.
