Weird cramping/dull abdominal pain

Rachel
So I'm supposed to be on my third day of ovulation and my cervix is low, firmish and I'm having dull pain in my uterus area. Just had a baby almost 5 months and 3 weeks ago. It feels as if I'm gonna start my period again... Any suggestions as to what's going on? Btw there's no blood, just creamy white discharge.
