Neesy • Mother
I'm TTC .. 4 months now .. I need motivation. I'm very healthy & doing most things right .. It's annoying how I tend to feel sick have weird cravings, pains and soo on.. But I'm not pregnant for All I know .. 
I'm still trying and praying 
What more can I do ? I've been told to take prenatal pills .. 
Help y'all ?!
